Anybody have one of these?

I have one and like it, but most of people playing with me prefer fresh new opened balls to 1.5 hours used ones out of this yellow can.

Yea. agreed, fresh can is always better, but does this really keep the pressure they were at when you finished your last game or is it just hype? i.e. is this a whole lot better than putting your used balls back in the tennis ball can and reusing them another time to practice serving. Scientifically it can’t possibly add pressure

I have two of them, one at least twenty years old, and another less than a year old. They prevent the pressure in the ball from decreasing. The balls will bounce about the same as when you put them into the saver, but won't be bouncier than when you put them in. The pressure mimics the pressure the balls were in the can before you opened it, which is enough to maintain pressure, but not increase the pressure in the balls.

I did just purchase a different device from https://www.pressureball.com/ that you pump up with a tire pump, and can get to a higher pressure. I haven't had it long enough to know if it really can increase the pressure in the balls.

i have one... never use it (forget to)... typically buy balls by the case, so almost always have a new can, or a just used set of balls in my bag. it works though, to keep'em bouncey, but for me, the fluff is the main killer that slows the ball down.

Right, I don't use the saver if the fluff is gone. But if the balls have been used for a short time and have fluff left, best to use the saver so the balls still have bounce next time you play.

Wow, so this pressureball tube in comparison to the gexco claims it can ADD pressure to already gameused tennis balls?

Anyone good at science care to explain that? Obviously you can inflate a bike or car tire, but how can you add pressure to a tennis ball without poking a hole in it?

Well, if you open a can of balls, but don't hit with them, don't they go dead after a while? The ball will leak pressure slowly. By applying enough pressure some air can leak into the ball. This is done pretty commonly with other systems for rejuvenating tennis balls.

How does a ball lose pressure? You are simply trying to reverse that.

These devices (I have one, rarely use it though) simply try to stop the losing of pressure and in theory could add pressure if they could compress the air inside the container enough, and maintain that for a long period of time.

There's still lots of really small (sub-microscopic level) holes in the ball that the air can get in through. As long as the pressure outside the ball is greater than the pressure inside the ball, air will (slowly) flow into the ball until the pressure on the outside matches the pressure on the inside. Balls lose pressure when they're in a lower pressure environment than their interior pressure.

I keep 3 of them in my bag to practice serves with or play fun matches. Works great. I throw the balls out when the fuzz is too worn down. If the balls are in them a week or two, I open and close them, because some of the pressure will absorb into the balls after a few days and that re-pressurizes it. If it's hard to open, just rap the bottom against the pavement 2 or 3 times and it opens easily. .

But yes, it works. Squeeze a ball that's been kept in one a couple months, and it's as hard as a new one, or very close to it. The key is to use it consistently, starting when the balls are brand new, NOT after they've been sitting for a month and have turned to mush.

I have several that keep balls pressurized. Use them until the fuzz wears off, which on clay takes a while. Good money saver if you ask me.
I play practice sets and drills with my wife 4 days a week, so we get good mileage from them.

I have this. It works. Trick is getting the right pressure. Too high and the balls bounce like superballs.

The ideal pressure is 1 bar or 14.5 psi. So you figure this would be easy to get the right pressure, right? Well, go to the store and buy 10 pressure gauges. I can pretty much guarantee you that they won't all give the same reading. So the way you actually find the right pressure is by trial and error by using the same pressure gauge.

For me, this thing works. But I never use it.

1) I want new balls for a match
2) I want new balls for practice
3) For serve / ball machine practice, I use Tretorn pressureless balls.

A new can of balls costs a bit over $2 at Wal Mart. It's for sure worth $2 to me to have new balls most of the time.

Gamma makes one also for half the price. It’s clear. Might be cool to watch the science in action ;-P

In the past six months I noticed Walmart Extra Duty Hard Court Penns went from 1.99 to 2.29 or something like that. Ain’t that about a b!tch

Never actually seen anyone use one of these. Everyone I play with and am around just uses new balls every time. If you are going to play a match with new balls why wouldn't you practice with new balls as well.

Yea, I don’t own one either and like to crack new cans as well, I was just curious about the science behind it

Show some gratitude and buy from TW. I buy a case of 72 balls at a time from TW.

They don't sell high altitude cheapie balls.
I just ordered 2 of the Gamma ones from a TW competitor, sorry TW you only had the racquetball one. Will see how they do. Good for service practice if anything. I hate balls getting dead in a hopper after a week.
