GAMMA BallHopper Hi Rise 75 w/Wheels, Multiple Colors, Pro Plus 110, Whopper 140, Durable and Convenient Tennis & Pickleball Hoppers, Padel, Portable Design

Purchased the Hi-Rise 75 to use instead of my Pro Plus 110 (both Gamma) because I needed a a basket that could hold a case (24 dozen/72 balls) of balls with out the size and weight of the 110 (that I've had since 2012 and love). My previous 110 has been very sturdy and flawless with the added Gamma Ez-Go wheels (2 sets). with slight modifications (epoxied the wheels so they don't separate, and used zip ties to keep the legs from popping off), I've actually filled it with 110 balls (Tretorn Micro-X for my tennis machine) and stacked a Wilson 75 ball Hopper (filled with old balls for serving) and rolled them to and from the courts for 5 plus years without a single issue. I liked that I could completely remove the lid (every use) so its not flapping around but when installed, the basket could be stored in the trunk on its side with the balls never falling out. Now that I hit with a little more power and lot more top spin, my machine balls don't last as long. So instead of buying and using 1.5 cases of Micro-Xs ($145 per 72/ $2 a ball) every 4 months, I've decided to just use one case of 72. Since my $20 Wilson 75's leg bent (thinner, cheaper metal) after a few months I decided to go with the tried and true Gamma brand. Once I received the Hi-Rise 75 I immediately noticed that it was much smaller than the Wilson. So I decided to see if it would at least hold the case of Micro-Xs. Exactly as suspected the Hi-Rise Could barely fit 65 balls with the lid closed! Even if I tried fitting 70 balls (as pictured) the balls would start to pop out the sides and push the lid open. not something you want if you have to lay the basket of balls on its side while in your trunk! So Back to Amazon it is going. Now, why I still gave it 3 stars. First while the hopper its self is heavier than the Wilson, It is much sturdier, stronger, and better built. I like that I still have the option of removing the lid. if this is an issue, simply use a pair of pliers to pinch the the retaining wires tighter (I do the opposite to ease daily removal). The rollers on the bottom ease slight movements of the hopper when it's flat on the ground but could also be removed (or not) to add a pair (or in my case 2 pairs) of wheels to roll the hopper around when its full of balls. I also like that the legs use friction instead of actual clips to stand the basket up unlike the Wilson that uses little hooks that get caught on things and have to be individually on clipped. This is especially annoying when you are done serving, have a racket in one hand, and trying to collapse the basket with the other. I have never had a problem of a ball hopper not standing and staying up right while in use (I don't even clip the all the legs of the Wilson, just on on onside). Lastly, YES the sticker with the name is cheaply and poorly made, so I used Goof-off and simply remove it (I did this on my 110 and 50 (yes I have a 50 too)).In the included pick you can see my old 110 with the wheels, Centered is the Hi-Rise 75 with 70 balls and no lid. To the right is the Wilson 75 with 70+ tennis balls and the lid closed. If you look closely at the bottom of the Wilson, you can see the little hooks that lock the legs in place. Also you can see the zip ties that I use to keep the legs from popping off. Recently (today actually) I switched the zip ties on the 110 to safety wire to make it more permanent, thus the missing zip ties on the back leg.

I loved this product initially. Perfect size, doesn't require you to hold your arm out to avoid hitting your leg when picking up balls. However, after a few months of normal use a couple of times a week, the handles separated, and now I have to figure out a way to solder, weld, glue, or wire them together. A friend has the same product and had the same problem. Manufacturer needs to come up with a way to weld the two sides together an then put the plastic tube over them for the handle, since whatever they're doing now isn't cutting it.

The concept for this design is very simple however the leg locks are not close to thick enough to prevent the legs from preventing the legs to spread apart and collapse. The diameter of plastic leg locks needs to be 1/8" or more larger for the locking to work properly. I could find thicker plastic tubing at the hardware store to make the locking to work reliability but I am not willing to do that for a brand new item I just purchased. I suggest people don't go through the trouble of ordering because the locking design simply does not work.

I bought this ballhopper for playing tennis with my children. Although sold as new by Amazon, what the company sent was a previously sold, returned hopper whose handles' ends were marred where they fit inside the horizontal tubes that act as a hinge for the handles.The ballhopper can be easily assembled -- to insert the handles' ends inside the holding tubes, make sure you keep the ends of the each handle separated by a few inches longer than the width of the cage to facilitate creating a insertion angle.The 90 ball-packing claim is false at least for standard tennis balls. Its cage is a truncated pyramid or frustum (that is, a pyramid whose vertex is cut away by a plane parallel to the base), whose top face is 10 x 9.875 inch, its bottom face is 8.5 x 7.625 inch, and its height is 12.5 inch. The volume of the cage therefore is 1015.23 inch³. A new pressurized tennis ball (Penn2) is 2.58 inch in diameter, so its volume is 8.99 inch³. For spheres equal in three dimensions, the densest possible packing uses ca. 74% of the volume, so the upper bound of the maximal packing for this cage would be about 84 balls [(0.74 x 1015.23) / 8.97] in the best-possible ever case, which less than the claim.In fact, unless you are compelled by your geometry inner demons to create perfect sphere packing in cuboids each time you play tennis, the packing is always more random than the ideal case in real life. Since random close packing uses ca. 64% of the volume, the most likely (and truthful) upper bound is about 73 balls [(0.64 x 1015.23) / 8.97]. Even with some balls protruding a bit between the metal rods forming the cage, the Gamma hopper cannot hold 90 playable tennis balls inside with its lid closed.

The legs keep falling off. I had to duct tape the legs together to keep enough compression so that when you flip the legs from the holding position to the standing position they don't fall off. VERY VERY VERY frustrating when you tennis balls end up falling out because the legs fell off and then it hits the ground, the top comes off and balls every where. Not the quality from Gamma I'm used too.

Great hopper for the cost. Sturdy and bright so you can see it from a distance on court.‘Wheels’ are 2 plastic half circles shoved together so they are essentially worthless as they come apart all the time.... lost within a week or so 😂

It is another present. The recipient was very pleased but has not beenable to test it because of the weather

Good hopper. Only holds 65 wilson trainer balls if you want lid to fully shut. If more balls put in you will drop some when carrying hopper.Simple mechanism for keeping legs secure - very good - hopper never collapses. Overall pleased with this purchase.

For me, this was the first basket I've ever bought, and my god it helps!!! I was so tired of having to pick up balls every 5 points so this seemed ideal. Now I get an extra 1/2 of playing time in (at least), and serving practice is a dawdle!!! 75 serves without moving at all. The price is also great. No mechanical faults to report so far, as this basket feels sturdy and I'm hoping it will last for a long time. A must for serious tennis players!

The item was package in a plastic bag which meant the legs/handles had ripped though and were subsequently bent during transit. On first use of the basket the handles fell out 5-6 six times during a one hour session.Could not recommend.
