    Good business idea! Expensive as hell! And I doubt that it will effective.

    I've used another similar item. A pressurized cannister, holds 60 balls. You pump it up with an external pump to 15-17psi same as in a can.

    It works. It's not a gimic. Was able to use new balls for months as long as you were dilligent about putting them back in immediately after you played, and pumping the cannister back up. A bit of a hassle, but it maintains the bounce like a new ball indefinitely.

    I've tried new balls stored in their for months, with fresh out of can balls...no difference. What changes is the felt if you actually play with the balls. Once the felt's gone beyond repair, it's time to dump the ball.

    The link you have has a built-in pump, but the concept is the same. It's really just basically a giant pressurized ball can.

    I would recommend it to any tennis player who hates dumping balls with perfectly good felt into the trash.

    What I would do is buy a case of balls, dump 'em all in at the same time. And just remove about 9 at a time.

    Use those nine balls until the felt's gone, then dump 'em, and take the next nine balls out...repeat until the cannister's empty...and start over again.

    Love it, but it gets a bit monotnous to have to manually pump up the cannister (I have a high quality bike pump for this due to living in an apartment...the sound of an electrical pump is just WAY too loud for the apartment living, but ultra convenient and fast if you have a house with a garage or whatever.).

    It's pretty obvious from the photo that these are just the cannister part of garden sprayers without the spayer hose. If you really want to try this, why not go to Home Depot and just pick up a sprayer. And when you're not storing balls in it, you can use it on the lawn.

    It works! A client of mine insisted on buying her own balls and discovered that they'd look fine a few weeks later, however they would be dead. She ended up buying two cases of balls every two weeks. I told her about the unit that was sold by ATS at the time. I was skeptical, but if properly stored in this unit right after use, they would remain lively for the life of the felt...

    The pump sprayers I have seen at Home Depot do not have a large enough opening at the neck to fit a tennis ball. I was thinking what about one of those air tight dog food buckets, the ones with a screw on lid. Then drill a small hole in it so that you could install an automotive valve stem. Then you could easily fill the bucket, and pump it up at any gas station or use a bicycle pump.

    I just use the Tennis Ball Saver yellow canister that holds 3 balls at a time. I have 12 of those for my 36-ball hopper. At $8 a can, that's almost $100. It's a little bit of a hassle to have to close and open 12 cans each time I play, but it's not that bad. They seem to hold up the pressure OK after a couple of dozen sessions, but of course the balls won't be as firm like when they're brand new. I would love to be able to store them at a higher pressure than 14 psi like match_point can with his container.

    The ball savers won't really recharge dead balls, but they should keep the pressure from leaking out of good ones and therefore extend their life a bit, provided that you don't pound the pressure out of 'em with your hitting, first. ;)

    For recharging, I've seen this, too. It looks like a pressure cooker with a Schrader valve.

    I built my own repressurizer out of PVC and an automotive valve stem. Total supplies ran about twenty bucks, although I spent double that buying parts that ended up not working. Honestly, I'd say that the whole thing is really not worth the effort for most people. At 35 psi, it still takes well over a week to recharge a flat ball. Also, no matter what you build, you will have to pump in new air at least daily. If what you build is at all shoddy, plan on pumping every couple of hours. (And I absolutely cannot overemphasize how difficult it is to build something capable of hold compressed air without significant leakage. I really underestimated the difficulty of this when I began building this. Air molecules are really tiny, and they really want out.) Still, I like mine, and it really does work, but I'm always nervous that the kids or cat will start messing with the valve (which is epoxy-ed in) and find out about explosive decompression the hard way. It's actually kind of a dangerous thing to have lying around the house. Why mess with it to save a couple of bucks a can?
