Gamma Revive Tennis Ball Pressurizer – Pressurized Ball Saver Storage Canister, Keeps Balls Fresh, Preserves and Restores New Ball Bounce

This product is well worth the price. I bought 2 of them and always keep my 6 tennis balls in these between games. You will get at least an extra month of use out of the tennis balls which pays for itself very quickly. If you play very infrequently then this is even more vital to keep the balls fresh for months and months. I play about 3 times a week and normally without this I am replacing balls every 2 weeks as they go flat.

This product is fantastic! I've used it with a new can of balls, and they've held up remarkably well through five practice and match sessions across two weeks maintaining a great bounce. I did have to replace the balls after the felt began to show signs of wear, but the bounce was just as if you had a fresh set of tennis balls every time.

Poor quality control. Huge gap between the o ring and inner wall. No way it will retain any pressure. I put some parafilm or tape under the o-ring to fix the huge gap. It now holds pressure much better.

Worked well in summer

This thing works. No other way to put it. The outside of the balls wear out before the ball losses pressure when stored in this thing in between playing days. I am ordering another one.

Loose gasket, always need to rotate when opening, never pull straight out after you've unscrewed or the gasket will roll off. The yellow ball saver seems to be better built.

Excelente producto

This thing really does work. Played with balls a month old and they were like new. Totally worth it!
