GAMMASports Pressureless Tennis Balls Box - Ideal for Practice, Teaching, and Training with High-Visbility Felt - Indoor and Outdoor Court Play - 48 and 75 Pack Sizes

Bought these for my dog. Perfect for fetch: the color is bright, the size is standard and they seem to have great mouth feel.

I didn't count them like others did, but looks right. Balls have great bounce. Using them for ball maching and ball feeding. Will order again.

Price is a little high, they are a great quality but if your buying them to throw for your pup you aren’t really interested in the right smell of the ball. I didn’t realize that the Smell and Look look and the Feel feel of the ball was important. Or if the Color is the best or is just the right shade of green the dog likes the Color weather it’s the Color green or the Color of dirt. It’s just easier and cheaper to buy the used box, your gonna throw them and get them dirty any way. It’s a ball so it preforms it’s function for a higher price.

Used these in my ball machine but be advised that many of them probably at least 15 of them right out of the box were completely flat. For a pressure-less ball this means there is a crack in the rubber underneath the nap (ball fur). In retrospect I should have just shipped them all back. I would advise doing a bounce test on all the balls out of the box. With an underlying cut in the rubber even with a pressure-less ball this creates a problem when the ball machine wheels grip the ball and they will not launch properly; you can still use them for serving practice as I did but it's pretty bad to have at least 15 of them dead out of the box. So it makes me think these are "seconds" the factory is unloading in bulk; somehow rejected QA in the factory in Thailand. Hope this helps.

If your dog is a certified "ball surgeon" like mine—peeling covers off tennis balls faster than I can say "fore!"—this bulk pack is a lifesaver. Or should I say, a time saver. Because no matter the brand, these are temporary.The GAMMA Pressureless Tennis Balls give me just enough time to enjoy a cup of coffee before hearing that telltale “crunch-crunch” of another tennis ball meeting its demise. But hey, at this price and in this quantity, it’s like a never-ending supply of doggy entertainment.Pros:Bright yellow and easy to spot in the yard (until your pup’s slobber turns them into swamp green).Solid bounce for both tennis and fetch!Bulk pack = fewer panicked Amazon orders when you realize you’re down to the last intact ball.Cons:None—unless you count my dog’s sheer determination to destroy them all.Verdict? These balls are a worthy investment in your dog's happiness and your own sanity. Just don’t expect them to last more than an hour in the paws of a true destroyer. 10/10 would recommend, 1/10 chance they’ll survive my dog. 🐾

I am a USTA 4.0 and former PTR Adult Develpment Teaching Professional. I have a ball bachine and spend several nights a weeks, just working on my groundstroakes. I recently purchased a 48 bucket of pressureless balls and noticed the balls were coming out of the ball machine very inconsistently. I thought maybe it was the machine until I started comparing the bounce of the balls from the new bucket against an old ball in the machine (and I have better things to do with my time that go through 48 balls identifying which ones don't bounce). 1/3 to 1/2 of the balls from the new bucket bounced only 70% to 80% as high as one of the old balls (ironically and older Gamma ball). The ones I IDIDN'T throw away weren't great, they just weren't as terrible as the others. If you are looking for pressureless tennis balls STAY AWAY FROM GAMMA. I'm about a good deal as well, but when you factor in throwing away 1/2 the tennis balls becuase they don't bounce, the good deal isn't so good. Now I'm going to have to purchase additional pressureless balls from a more reputable company.

My golden retriever loved these.

The first set of gamma balls I bought a year ago, came in a sealed plastic container and they were great for the ball machine. The ones I received this time came in a cardboard box and they appear to be mixed levels of firmness which makes play in a ball machine very frustrating.
