“Thank you Paul for letting me have your innovative SlingHopper Pro. I have an 11 year old grandson who loves to play tennis. The SlingHopper is perfect when I have to work with him on the court. I have tried boxes and bags and carts, but I always seem to find a chair to rest them on. The SlingHopper sits right on my body allowing me to move around and not have to bend. 

Even if you have access to a basket or ball hopper, the SlingHopper is much easier for the pro or amateur. They now have the freedom to ‘fill it up’ and create various feed selections. 

I wish you well with your innovative approach to ball feeding and would certainly recommend the SlingHopper Pro to any teaching pro and player.”

– Fred Stolle

“The SlingHopper is the greatest innovation for teaching in a long time. It allows us the pro to move around the court without interrupting the flow of the drills. The SlingHopper makes teaching easy and fun.”

“The Slinghopper is great when I am traveling with touring pros, I used to carry about 20 balls with me and keep them in a box. With the SlingHopper I can carry as many balls on the court, feed and hit out without having to bend down for more balls. The SlingHopper folds up pretty easy making it idea for traveling.”

“The SlingHopper drill bags are simply the best tools for feeding and rallying. With the SlingHopper Pro I am able to move around the court and “feed on the fly” without having to worry about grabbing more balls from a cart. When I am rallying with my kids I am able to develop better rhythm and pace. I can easily change from a hitting mode to a feeding mode.”

“I travel up to half of the year and having the Slinghopper with me has made coaching from anywhere in the world much easier. It packs easily and is a necessary tool for successful coaching. More and more wheelchair tennis players are being certified as coaches working with seated players and able-bodied players. The Slinghopper is a perfect fit for seated players and coaches alike allowing them to be mobile as well as alleviating the need to reach up to a basket of balls which only slows a drill down. All seated players and coaches should make the Slinghopper a part of their every day tennis equipment.”

– Dan James

“Have you ever watched the lack of energy and excitement in a tennis lesson where a pro stands behind a shopping cart? That will not happen with a SlingHopper, as the professional is freed up and can truly be involved in the lesson with lots of movement and excitement. Every student should thank the SlingHopper for bringing the professional back into the lesson.”

– Peter Burwash
President / Founder
PBI International
Carmel, CA

“I was definitely skeptical at first as to how useful the SlingHopper Pro was going to be, but after using it for one week, I don’t ever want to be without it. When feeding live ball drills where the pro is involved, it is invaluable no to have to go back to the hopper after every few balls. When multiple students are serving, I can move around and give them balls so they don’t have to go back to the basket. It simply allows me to be a better professional. I love my SlingHopper!”

– Howard Chodak

“My staff and I have found the SlingHopper product to be most helpful. When you are managing several courts during a drill or match play session, you never run out of ammunition. When we conduct Cardio Tennis classes, the SlingHopper helps because the on-court teaching professional needs to be mobile- while having access to plenty of balls to keep the class moving briskly. My staff and I certainly appreciate any product that makes our job more convenient.”

– Bill Mountford
Director of Tennis
USTA National Tennis Center
New York

“I am amazed that no one else has come up with this sooner. I am impressed with the fact the SlingHopper allowes me the simple freedom to move around the court and feed balls. In all my years as a tennis coach I have always fed from the same spot moving my hopper only to re-position. I can hold about 7 balls in one hand but I often find it awkward to feed. I wish you the best, wonderful concept.”

– Dr. Martin Baroch
Founder of the Czech Professional Tennis Association
Director of Education
USPTA Master Professional

“In implementing a games-based approach to the teaching of tennis, the Slinghopper is a wonderful instructional aide which allows me quick and easy access to the supply of tennis balls so that play continues uninterrupted. I am now able to move with freedom to any position on the court, and start the play/point from anywhere without pulling a teaching cart with me wherever I go.

I especially appreciate the benefits of the SlingHopper as I work with the Gamma Revolution ball, as the larger foam ball fits easily into the pouch, and I am able to access them quickly without the need to attempt to balance the larger balls in one hand as I begin the point or skillwork.

Please know how much I appreciate your efforts in pioneering this excellent teaching aide. Best wishes for your continued success, Paul!”

“I’ve been using the Slinghopper since you sent it to me. It is truly a unique teaching tool. When your on the road as much as I am covering an entire state promoting, teaching and coaching the game of tennis for the USTA, it is a very handy device. I always know that I can be anywhere and have the balls I need to present on court activities. Thanks so much for making my job easier.”

– Alicia P. von Lossberg

“The SlingHopper is a great and useful item! I use my SlingHopper for my outdoor lessons and I fill it up with balls before each lesson. All I do is strap it on and I have no worries, no hopper, no basket getting in my way. The SlingHopper is also great when I am transporting from court to court.”

“To a teaching professional, the invention of the SlingHopper drill bags is one of the most innovative ideas to come into our sport in years. Instead of being stationary next to my ball cart, the SlingHopper gives me the flexibility to move around the court and to feed balls from any position on the court, thus allowing me to vary my drills, and to make my lessons more exciting for my students. My students have greatly benefited from me moving about the court and firing balls at them from all angles, therefore simulating real match play. Thank you SlingHopper for making me a better teacher.”

“What a pleasure to coach with the SlingHopper !! I often move around to and from many courts without the hassle of a cart; the soft comfortable picking of the balls spares my hands the nicks and scrapes of traditional metal ball hoppers. I use the SlingHopper on the road for easy storage and convenience when working with kids, GREAT IDEA !!”

– Geoff Norton

“I love the SlingHopper Pro! It is especially useful to me when working on “live” drills involving court positioning and strategy.

– Simon Paek, USPTA

“Paul, thanks for my SlingHpper Pro!! As a national level speaker and trainer for Wilson, the USPTA, PTR and USTA, the SlingHopper has made my on-court presentations more efficient. I always know where the balls are when I need to demonstrate a skill or drill during a presentation. The SlingHopper Pro cuts my tie to the teaching basket. When I am doing matchplay drills with groups, I am free to roam around and give individual attention to my students. I always have a ball by my side when I need to demonstrate a tactical situation, feed a ball in for a drill or move around the court when I am involved in matchplay situations.”

– Ken DeHart
USPTA & PTR Master Professional
Director of Tennis / San Jose Swim & Racquet Club

“I am a British Tennis Coach and recently received my Slinghopper Pro.

Keep up the good work and I hope more British LTA coaches get to see your product; all of the coaches that have seen mine seem very impressed.”

– Andrew Reynolds

“The SlingHopper is a great aid helping to develop ground stroke depth and directions. With 15 to 20 balls in the SlingHopper, I move closer to the net in a diagonal line and practice hitting my shots to the two extreme corners and the two sidelines. Highly recommended.”

– Cheung
New Milford, NJ

“The Slinghopper is an outstanding tool that gives the coach the freedom to move around the court while drilling students. I highly recommend this product to coaches who teach the old fashioned way. It is an inventive way of conducting drills by allowing you to be more involved in the game play and not anchored in one spot. You become a mobile ball feeder that can interact as well. It’s a great product.”

– Matt Gilbert
Boy’s High School Tennis Coach

– Neville Batiwalla

Bloomington, IN

“I just used it today at a Special Event hosted by Sports Illustrated and Dodge. It was wonderful to just reach in my “bag” and pull out Star Balls to use at a mini tennis net. I use it for all my lessons..and now I can move around. It is especially great for Cardio Tennis!”

– Bobbie Campanaro
Independent Teaching Pro

“To say it simply, the SlingHopper has freed us to move. We are more involved with the adults, the assistants are more involved with the juniors. I ordered 1 for myself, realized what a good thing it was and ordered 3 more -(1 left and 2 right). I have always been a playng Pro so to have the ability to step away from the basket is a good thing. The SlingHopper is a great tool.”

– Miles Harris
Director of Tennis
Laurel Creek C.C
Mt. Laurel, NJ

” The SlingHopper is excellent for use with Special Olympic athletes since many of the balls do not come back to the feeder. It is also easier to retrieve balls near me and put in the SlingHopper. The athletes are eager to help retrieve balls and feed my bag too. I also eliminated the problem of balls hit into the hopper and the hopper falling and spilling balls all over. “

– Lenore Gleason
Special Olympics Coach

“I use the SlingHopper rally with almost every lesson I teach. It allows me to move during group drills to give a more realistic feed than being in one position for the entire time. I like to use it with hitting lessons. When a ball goes out of play I can feed in another so the play becomes continuous. Great tool to build endurance. Wouldn’t want to teach without one.”

– Richard King

“I love my SlingHopper, and the versatility it gives me in teaching. When it is empty, we switch to a new team, I like how I can move and feed from several locations on court without moving a basket. I ALSO like that I can keep my left hand free when doing drills with students. Holding several balls from a hopper hampers me since I need my left hand to prepare for backhand volley.”

– Bobbie Campanaro

“I coach school tennis and a member of USPTA. In my school team tennis I mainly am working with a group. I don’t like the cart getting in the way when I am drilling beginners. They tend to spray the ball all over the court. The SlingHopper Pro has improved the way I can teach the skills in both group and priviate lessons. I can change the place I feed the ball from in a split second and change the drill by doing so, thanks for a great tool.”

– Zack Morgan

Pres. Lake Powell Community Tennis Assoc.
Page, AZ

“There are plenty of old school, snobby tennis pros, who think it looks silly to wear this thing, but I always tell them, “I’ve got 30+ balls on me and you have 4.” I basiclly use it for team drills. Gives you the flexibility of moving around the court, to feed from anywhere, without rolling the cart with you.”

– Richard McMichael

“I initially purchased the SlingHopper Rally to practice serving, as I practice often, but I have begun to use it for drills with friends. It is perfect for it carries a sufficient number of balls and it does not hamper my strokes whatsoever. It is light in weight and it almost seems that I am not even wearing it around my waist for it is so well designed. All my friends want to use it and are very impressed. I would recommend the SlingHopper to a player at ANY level.”

– Barrie Street
North Vancouver, British Columbia, Canada

“The SlingHopper Pro has allowed me to offer my students a better lesson. Just like a real match, I can move around the court and feed balls to my players from all angles on the court. This gives me an advantage that I have never had before nor I have I ever seen. The kids want to grab mine and try it out when I take onto the court.”

– Jorge Capestany
USPTA Master Professional
President, Havana Bobs Tennis Shirts Hudsonville, MI

“The SlingHopper has been an awesome find for me! Teaching tennis from a wheelchair can be tricky when it comes to reaching into a ball cart that is always too high for me from my seated position. Also, there is the issue of: How can I hold several balls at once while I am teaching? WELL, the SlingHopper has eliminated these two issues. I am free to move around the court and not have the worry of constantly grabbing just a few balls at a time from a ‘too tall’ ballcart or having to stay near the ballcart at all times. Thanks to the SlingHopper I am a more “Accessible Instructor”!”

– Harlon Mathews
PTR Certified Wheelchair Instructor
Covington, GA

“The SlingHopper fits right into my teaching style. I am able to play and work out players, really push them without breaking the rythymn by getting more balls.

It really has changed the way I coach tennis.You have a great product and I love it.”

– Shinichi Suzuki

“I have received my SlingHopper, and just in time for the high school tennis season. I am a high school tennis coach in Marietta GA, the school is a small private school, but has had great success in our region with both the boys and girls tennis teams. With the addition of the SlingHopper, I am able to conduct our practices more efficiently than ever. No longer am I tripping over a traditional metal ball hopper or having to stand in one location for an entire drill. The SlingHopper allows me to be more versatile with our practice time.”

– Scott Cabrera
Teacher and Tennis Coach
Dominion Christian High School
Charlston, VA

“The Slinghopper Pro gives you the freedom to move 360 degrees around the tennis court without any interuption in feeding balls during the drill. Students benefit because, during any point, balls come from different angles at any given moment… thus simulating match play. It is a MUST for any Coach or Teaching Pro who is serious about teaching tennis and wants to be on the cutting edge.”

– David Altshuler
Tennis Director
Nahant Country Club

“Good afternoon, I wanted to give you my testimonial for the great sling hopper. My name is Rahima Abdul-Rahim and I have my own tennis CTA- Washington Area Muslim Tennis Club, located in Washington, DC. Before winter, I used the SlingHopper, it was just fantastic. It holds enough sponge balls to enable me to feed the balls in to keep the game going with out having to stop and pick up too often. It also holds a good number of regular balls too. The SlingHopper is lightweight, easy to put on, and fits all sizes of people. I may not have my PTR or PTA yet, but wearing my SlingHopper sure makes me look professional. I really have enjoyed using my SlingHopper.”

– Rahima Abdul-Rahim

“Paul, Here in Sweden we are very pleased with our slinghopper and use it all the time!!!! It has been quite cold but we play indoors most of the time. I use the SlingHopper to coach my girls and it is great for practicing serve. Some of my adult students put the SlingHopper on and drop feed forehands.”

– Anki Holm
Djursholms TK

“I want to take the time to comment on your great product. I spend a lot of time working with children and the Slinghopper has been a big help. Kids have a short attention span and the Slinghopper saves time and allows me to keep things moving. It also lets me have students on both sides of the net without having to worry about them running into the hopper. I keep the hopper off the court and let the kids pick up balls and fill it as a staging area for my Slinghopper. I don’t know about how other people feel, but hoppers are a pain! They’re awkward to transport, they rust, and they fall over at the most inopportune time. The only thing wrong with the Slinghopper is that I DIDN’T INVENT IT!”

– Roger Midgette
Silver Spring, MD

“I coach a men’s tennis team at a university and find the slinghopper a fantastic aid to my coaching. Storing many balls in that convenient pouch allows me to maintain the frequency of continuous feeding. This allows me to get my players in a better rhythm. The pace of the drills are fast and furious. It literally leaves my players breathless! Bottom lines is that the slinghopper maximizes our workouts. We love it!”

– Steven Bergovoy, USPTR
Head Men’s Tennis Coach

“I am a teaching pro. The SlingHopper is a useful addition to any pro;s bag of tools. I found for certain situations it works much better than standard hoppers.”

“The SlingHopper is great! I purchased one for my dad for Christmas (USPTA /Carson Newman Tennis Team / Assistant Coach) and myself (USPTA, but currently not teaching professionally). The Slinghopper has been great in teaching friends and family tennis without having to purchase a teaching cart or worry about where I feed balls from on the court. Also, one of the best parts is I can enjoy playing as well while still using the SlingHopper.

I highly recommend the SlingHopper to fellow teaching Pros, and also my friends who enjoy leading and or participating in drill sessions.”

– Marcus Pillion

“I am a teaching pro in Atlanta and I received my Slinghopper and love it. Great for teaching, and also for drilling with team mates and other pro’s. I saw mine at a seminar that Ken deHart was giving. Several pro’s who have seen mine have asked about it and where they can order it. I like it for teaching, it’s a great way to know when to rotate some drills, when the bag is empty, I rotate. No one can say I gave one group more time than another.”

– Bobbie Campanaro
Atlanta, GA

“My wife and I use the SlingHopper everyday to drill, I feed balls to my wife and it has helped her to go from NTRP 3.5 to NTRP 4.0 in 2 months by constant repitetion without having to lean over to pick up balls and not having to go back to the ball hopper. The Slinghopper enables me to quickly hit balls from side to side with speed and match simulation drills. I also can move it to my left hip and practice first and second serves simulating match conditions without having to stop, which also serves as a conditioning exercise.”

“I have used the SlingHopper and found it to be very functional. I have even been able to hit with other players wearing it. My only criticism is that I would have liked to have known that there was as smaller version although the larger one would be more appreciated if used on for teaching others. I use it mainly for practicing serves and the smaller version would have been adequate. Still it is a great asset brushing up on weak areas of play over the summer months on an outdoor court. I am so glad to have found this great tool for advancing my game.”

“I use my SlingHopper six days a week and love it. I am the new tennis director at Loudoun Sport and Health (VA). I got the previous director a Slinghopper as a going away present. He had back surgery last winter, and he says it really saves him bending over to get balls from the cart.”

– Patrick Sloyan

“The SlingHopper is a very helpful tool that I use in my tennis programs especially when I’m demonstrating “SHOT” selection, I used to HOLD 5 balls in my hand, but when I use The SlingHopper it makes me bale to relax and look more organized and Professional. Thank you very much for this great Idea. I recommended this a lot here in Indonesia to use when teaching.”

“I have just received my SlingHopper Pro and use it extensively; it is a great product to have. I have been teaching tennis at a private High School and will be the girls Varsity Coach next Spring. Initially they made a lot of fun about my pouch but quickly saw the wisdom when I was able to move them around more freely, feed them different angles and being able to return the shots that for some strange reasons were previously quite often too close to the cart.”

– Jorg Rauthe
Girls Varsity Coach
Tarrytown, NY

“Just received my SlingHopper Pro and I feel its a great product. I am not a professional coach but I do play with my kids and wife almost every week. I also use it to throw tennis balls to my son when he is batting, you should think about that too. Thanks!!”

– John A. Cuccia
Melville, NY

“I use my SlingHopper all the time! Mostly for privates, but, even during our junior program while my assistant pros are drilling the kids and I’m out roving the courts, I’ll keep my SlingHopper on so I can interject a drill or just break up the court a little. I always have my balls right where they’re suppose to be. Anyway, great new product. I’m thinking of stocking them in my pro-shop.”

– Bob Deller

“This product is a must for teaching professionals. It is convenient, handy, versatile and lightweight. I Am using it in lieu of the bulky ball hoppers that are a pain to move around.”

“Paul, it doesn’t surprise me that SlingHopper is getting a lot of positive feedback. Having my own smalll private and clinic clientele, The SlingHopper Pro allows me lots of freedom to move all over the court and ocassionally jump in to a drill to feed an extra ball or two to the players without having to reach into the basket to reload. A great idea sure to continue to expand.”

“SlingHopper Pro drill bag is the ideal ball carrying device for my coaching applications in developing patterns of doubles play via live ball point play with Women’s Interclub teams. Generally I play in one of the four doubles positions have players rotate from a line two or three deep into the “HotSeat” position. Depending upon the theme and pattern, I put the ball in play to the Hot Seat position and create an offensive or defensive situation. Players are told to rotate clockwise, skipping me over and we go at it the pattern over and over, playing out the point to conclusion. And, SllingHopper allows me quick access to balls with minimal down time to secure more balls from a teaching cart.”

“Great Invention !! I use the SlingHopper every day to hit with my wife – she is also a ranked player in Florida – I don’t have to chase balls and I have no problem hitting out, I do have a one handed backhand though. Every teaching pro should use one.”

“I love my Slinghopper. I have been using it when I’m trying make my students move more on the courts. I will play points out and when someone hits one into the net or out, I will be able just to toss another into the mix to keep the play going. Sometimes, I will add Speedballs or Champs and change the pace of the game. The Slinghopper allows me more flexibility than having to drag a basket around with me. In coaching, it allows me to move court to court without major equipment hauling. I feel more like a coach than a Clydesdale hauling beer. The Slinghopper frees up your hands so you can carry balls yet be free to hit and make points without having to stop and fill up on balls. I think that it is a great teaching tool, especially for coaching on multiple courts.”

“I have to say I love the SlingHopper. The SlingHopper lets me be the hitter and keep a drill going for as long as I want with no interruptions. The metal hopper is now used to fill my SlingHopper and to pick up balls. It is a great product and well designed.”

“I use the SlingHopper with every lesson. I love the freedom it gives me on the court and it is quick to reload. I have been a teaching pro for over 40 years and I teach adults and kids. The SlingHopper allows me to always have another ball ready to keep feeding or keep a point alive. With over 100 drills in my camp program I used the SlingHopper with my top junior players. The SlingHopper makes for a great drill time. I am a huge fan!!”

“Paul, I really enjoy the Slinghopper Pro. I especially like it for my hitting lessons. Our clay courts are a little harder to get our brute carts to, so I use it when I teach up on the clay courts. The slinghopper Pro is a valuable part of my teaching supplies.”

– Steve Curtis
PTR Teaching Pro
Springfield, VA

“I have used the SlingHopper Pro and found it very useful. I especially like using it with kids who are transitioning from ProPenn Stars to regular tennis balls. I fill the Slinghopper with stars balls and my cart is full of regular balls. That way when I want the kids to rally I have a ready supply of balls without having to go to the cart or to the side of the court. Thank you for creating another tool that helps make my job easier.”

– Dave Hagler

“SlingHopper Pro has improved lessons at our club in 3 ways : It keeps LittleTennis moving faster allowing us to feed star balls quicker, ladies clinics can be fed during point play form all angles of the court and the ranked juniors love the constant play during live ball drills with the professionals – great new product !”

“The Slinghopper Pro is an excellent tennis teaching aid. It has proven to be a very efficient way in conducting smooth clinics, group and private lessons. Whether it be youngsters or olders players, regardless of their levels of play, the Slinghopper Pro is a winner. It prevents me from being continuously attached to my ball cart. Mobility is the key to teaching a great lesson, and the Slinghopper Pro does just that. A definite two thumbs up!”

“I am a member of the USPTA and PTR and am currently Tennis Director of the Nahant Country Club in Nahant,Ma. I have been actively teaching tennis for 25 years … attending and speaking at both National and Regional USPTA conventions.

The “Slinghopper Pro” offers the teaching professional greater variety and freedom of movement during any drill session or instructional play. It allows the pro to feed from many different angles and because of easy access, improves student reaction time and over-all quickness. Regadless of my “feeding” position, I always have tennis ball access at arms length.

The Slinghopper Pro is a must for any “pro”, “coach”, or “instructor” to own… a great innovation that makes a postive and measureable difference for both the student and teacher.”

“Thanks for your email. The Sling hopper is a great tool for me as we do many group lessons and it helps with the Slinghopper full of balls ready to go! Whether I’m feeding or just supplying balls to my students, it is great tool. I tend to over stuff the Slinghopper and the weight of the balls I can feel later the strain on the lower back. If there was a shoulder strap to disperse the weight when loading up. Other than that, it’s a great tool for the tennis instructor.”

“I just ordered one. I am USPTA and PTR certified. I have been using the HipHopper but it is difficult to get the balls out. It looks like you solved this problem and I look forward to using the SlingHopper Pro!”

– Don Hull

“I am running an NTRP rating improvement class series where the students are learning, among other things, the necessity of learning to feed and drill. It would be interesting to see how they respond to using the SlingHopper and if they feel more comfortable and mobile. I have twenty students in the class and would be interested in seeing how the class interacts with everyone using their own SlingHopper rather than wheeling around carts and looking for hoppers from which to feed.”

– Michael Stenquist
USPTA Northwestern Division President
Minneapolis, MI

“I wanted to let you know how much I love the SlingHopper Pro. It has made my life on the court much easier. I don’t have to keep going back to the hopper or basket for balls. My students love the lack of down time between feeds. The SlingHopper Pro is lighter than I thought it would be and I have no trouble moving around the court even with 25 balls in the SlingHopper Pro. Thanks for making my life and lessons easier.”

– Steve Diamond, USPTA President
Montville, NJ

“SlingHopper is very good improvement on some attempts at this type of product – a tennis ball bag that goes around the waist. I have taken it out on the court and find it to be a wonderful addition to the teaching arsenal. Designed to replace the clunky metal hoppers, that just are pain to drag around and get to stand up, the SlingHopper is a comfortable, affordable, and “with-it” teaching tool.

It holds 40 balls, so it is not too cumbersome. You can move freely around the court, changing your feeding stations at will. I find this to be a great asset for teaching a player who can rally fairly well, and a real good thing to use when teaching the young beginners – when you want to get right up in front of them, and be able to move right on to the next student or hitting drill. Coupled with a large ball storage vessel (i.e. the rolling cart) this SlingHopper is just dynamite!”

– Paul Dayton, USPTA

“Paul – I want to thank you for being a part of the 2004 PTR Trade Show. Your SlingHopper booth was an absolute success and I do hope that you plan on joining us for next years trade show. We have had positve feedback from attendees, and we only hope to do our best to try and make the show even better next year.”

– Lindsey Baxter
PTR Trade Show Coordinator
Hilton Head, SC

“Brought the Slinghopper to work and the comments so far from students and other pros is that I was able to move drills at a faster pace than before and there was less student down time. I moved around the court more and was able to do more in less time. The large bag was great for my small students. They enjoyed wearing the bag as my assistant.”

“Slinghopper is the best teaching tool for working with little kids, especially in a “clinic” environment! When handfeeding to multiple kids on a court , I never lose eye contact with my students, because I don’t have to turn my back to grab balls out of a cart. It allows me to really keep their attention! I LOVE my Slinghopper!”

– Mark O’Bryan

“I purchased the SlingHopper for our club while at the PTR symposium. I have used it a lot and find it an excellent tool even for group lessons when I want to be in the middle of the doubles action and recreate the point. It has been nicknamed the Roo and also the Joey from the Kangaroo pouch it resembles. Thanks for showing me your product, we will purchase some more in the near future.”

“As a teaching pro and high school coach I have used the SlingHopper Pro and have had great success. We use the SlingHopper Pro with our students and team during fed ball and live ball drills. The SlingHopper Pro fits comfortably on the waist and holds a boatload of balls. This is a product that really lets the student groove his strokes.”

– Jay Barston

“In Europe, I often travel via public transport to different courts/locations and having a SlingHopper Pro is a lot easier on the arm than dragging around a heavy metal hopper, thanks for a wonderful idea.”

“I have used the SlingHopper Pro during my last 7 lessons. I love it. I teach 8th – 11th grade kids in one lesson group. I have coached high School tennis for 29 years until 1994 and still teach at Warhawk Tennis Camp in WI in July. I plan on using it there and in all my lessons in FL and WI. I am a USPTA pro at two clubs in FL and the SlingHopper Pro helps an “Old Coach (64)” from falling over a ball hopper when I play out points. It was money well spent.”
