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

Very disappointed with these unpressurized balls. I am a competitive 4.5/5.0 player who just got a Lobster Elite 1. I bought these balls based on the generally positive reviews and good price. I haven't played with them off the ball machine and will have them back soon. I was surprised at how different the balls felt when hitting the club and getting out of the car. You don't have constant pressure, that's the whole point of buying without pressure. Some are hard, some are very soft, and I haven't found them play anywhere remotely like a normal pressure ball. Felt covering is also not suitable. for advanced players. I don't hit a lot of topspins, and after hitting them, only the fourth or fifth hit and the felt started fuzzing and peeling. Micro X is better.
