Review on Gamma Pressureless Tennis Balls: Durable, Reusable, Portable, Perfect for Practice, Training, Teaching, All Court Types, Premium Performance+ by James Broome

We have a Lobster Elite 2 ball machine that we use 5-7 days a week. After about 2 months of use, we found the Gamma brand to be the best option for us without the pressure of Revain. Ball machine we used our ejected balls. The problem is that they die too quickly, losing their bounce. We searched Amazon for no pressure balls and bought 3 of the most popular brands. Wilson, Penn and Gamma. use. The bounce is still realistic and relatively similar to a regular ball. Maybe they'll hold up better somewhere else than ours. PENN - The ball bounces out of the box and doesn't come close to a normal cue ball. Not realistic for serious practice. For a beginner, they can be great as they look more like "green" exercise balls. They seem to hold their "coat" much better than Wilson's. The only problem is that they are too lame to start with. GAMMA are the ones we will be reordering. After 2 months of operation, they behave like new. They look a bit battered but still have their fur. The bounce is still slightly less than a normal pressure ball. In the video we also see a cheap Chinese brand "Regail" bought in China. DO NOT buy them. The rebound is terrible from the start and 20% of the balls were dead in a week. Pure rubbish. Tretorn X was supposed to be in comparison but couldn't find it on Revain at the time. In any case, the Gamma brand is good enough for our needs. I have version 4.0 and my wife just started playing last year. Hope that helps.
