Which Pressureless tennis balls should I buy?

I'll use them with a tennis ball machine.

Unique Pressureless Tennis Balls
Tretorn Micro-X
Gamma Pressureless Tennis Balls

Which one feels closer to a Wilson or Penn ball? How long do they last?

The Tretorn Micro-X balls are the best. I bought Unique balls one time and when I opened up the bag, all the balls were dead.

I bought today 2 bags of unique balls, and I have to tell you that they're really good balls(at least the ones I bought), they're just a little bit heavier than wilson balls and they bounce pretty close to wilson balls.
I'll buy a couple of Micro-X cans next week so I can have an idea how heavy those balls are. I'm worried about comments mentioning that they're really heavy balls.
I have bought a bunch of the Gamma balls. I have poor experience with them. The rubber cracks and they go compltely flat. I've had no less than 6 out of 48 crack within two weeks time.

I know I don't hit then THAT HARD!

I would like to try Tretorn but I don't have a good source.

pressureless balls

All the pressurless balls stink. I use gamma, they are durable but are heavy. I got some Micro-X samples. They are like rocks. The Unique balls I got were sort of OK for the couple times I used them, but they lost their fuzz quickly. When I use them in my ball machine, I get tired of hitting the hard balls over and over. When I tried to rally with Micro-X, it was a pain hitting rocks and watching the ball sail. They do not substitute for real balls, but can be useful in practice at times.:D


It's been my experience that Gamma pressureless balls turn to fuzz in my ball machine. I've had good experience with Penn pressureless balls. They hold up pretty well.

Tretorn pressureless are the best out there hands down. Have not used the micro-x, I’m talking the pressuerless ones and they are used in pro tournaments overseas. They last forever. They play a little harder on the wrist, but they are the best for machines. Pros complain they cause injury, but that has not been substantiated.

I've used JUGGS and Gamma. So between these two JUGGS had better live span with TT ball machine and they didn't have that "hitting rocks" fill. Gamma were cheapper though.
