I've used these for 15 years now. There are two usage cases: 1 - New balls that you've used and want to stop from going flat. Put in the container after using and they'll be much better when you play again in say, 1 week's time as they don't lose pressure. 2 - Balls that are already pretty flat. Place them in there, leave for a few weeks, take out and put back in again (to get the pressure back up inside the container as some will have already gone into the balls). The old balls will definitely be really nice and bouncy again. I used to play 5 times a week and had 3 containers that we cycled through. We would throw balls out because they had no fur left anymore, not because they had gone flat. I am now in the process of building my own with some PVC pipe and a bike tyre valve so I can re-pressurise bulk amounts of balls. P.S. there is no quick fix sorry!
Also, I used the clear Restore ones, and my mate had the Yellow and White ones. The clear ones worked better I thought, but I've had a few of the clear ones seize up on me and had to break them open
hello ! How did it work out your bulk pressurizer? I'm wondering if I can do the same using my plastic backpack fertilizer cannister which is a large reservoir with a manual valve that pressurizes the interior to insane levels!
Both of those should be relatively identical. Brought to market in the 1970s, the patent has long expired and it appears the Tourna is just a legal knock-off of the original maker ( I own both). Interestingly, the original still sports the same 70s style graphics... BTW, these should be used to keep your freshly opened balls in shape-- not so much for restoring dead balls...
You could let the ball with more time inside the can, maybe a day. Probably it would give more result to reviving the ball. But the difference it gave in just a minute can say a lot that this actually works. That's impressive.
Do these renew the balls or keep them new longer? I had one of the yellow cans for racquetballs when I played and it did keep new balls bouncing well longer. I don't think there is anyway to refresh old balls.
Sadly you got the concept all wrong. The main purpose for these containers is to keep recently opened balls fresher for longer. It is not meant to bring flat balls back to life, rather extend the lifespan by keeping your balls at a high pressure whenever they are not in use.
I have been using both these products for years w no real preference but this was interesting to see. In my experience these are both great for preserving the bounce in balls but questionable for actually restoring bounce. Here are a couple additional thoughts. These products keep the balls pressurized but you are also playing with rubber balls which lose pliability over time. This cannot be restored. Also eventually the felt will wear off. I get 50 percent more use out of my tennis balls and then have to replace them after. Also, if environmental impact of buying balls makes a difference consider these products. Tennis balls cannot be easily recycled due to the multiple components felt, glue, etc. making up each ball not to mention the packaging that goes into each ball, cans, plastic wraps etc. From an environmental standpoint it makes sense to use your tennis balls as long as possible. We donate our used tennis balls to the local animal shelter for dogs to play with. Thanks for the great review video!!
Best way to repressurize is keeping in canister at least a week as suggested. In instructions. From physics standpoint putting balls in while air is colder will yield greater pressure as pressurized container warms up p=nRT÷v. And use nitrogen of you can find it like at some warehouse club tire centers in a pressurized old keg
I think it’s good if you have like 3 new cans in your bag, and you open one up to play a game but still have the other 2 unopened, you can at least preserve the open can until you play again. So it’s cool. And it don’t take any more space. It still is like have a can of balls in your bag.
Logically, if it takes fair amount of time for balls to lose pressure, it will also take a fair amount of time to re-pressurize them. It's not quick either way I'm surprised that 1 minute does anything useful. The goal in my mind is to put balls you've just used in them mostly to avoid losing pressure between uses, be it a day or several days or more. If you want to restore older balls to new bounce, it would make more sense to over-pressurize them to force air back in the balls quicker.
These types of pressurizers that develop pressure without a pump are very rarely effective. They don't develop enough pressure to 'restore' balls. I had a number of them and most of the time the air leaks out in a few minutes and they do nothing to preserve the balls, the weak seals are just not effective in maintaining the pressure. The pressurizers that work have better seals and allow a pump to be used to create the higher pressures required to do restoration of ball pressure. 20 to 30 psi is required for restoration, and it takes time as in weeks to do the job. Not all balls improve, but many do.
Hi bro, try using Pressureballs tube, it really better than yours. You pump the tube till like 20 psi, then the old soft balls will revive it, but after few weeks, put tube back to 14 psi to maintain them.
review not good. these are for balls that are not too old. Its for fresh balls that you have used for some sessions that has lost a bit of bounce. then you put them in the pressureizer for 1 day and they have gotten the original bounce back. its to make the balls last 3 x longer.
For another video you should do what it says and leave three balls in each can for the 4 weeks or whatever. Maybe even use balls that were opened and used for around the same amount of time (or just open 2 cans and leave them in your bag for a couple of week so they lose the pressure). I think that'd be a better test group than what you did by picking them up off your garage floor lol But anyhow, great video and many blessings. - Emmanuel
What doesn't make sense to me is the fact that the air we breathe at sea level is pressurized at 15psi. Do you think these cannisters instructions actually mean they add an additional 14psi for a total of 29psi?
both of those (that type) containers only work well when they are new, as soon as the inside bore/wall gets scratched, the air comes out be-fore it gets into the tennis ball. Best make your own one, like this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HFCj4ZVAWfs.html
10 mins to basically say a whole lot of nothing. All you need to do is: 1. Show bounce before with actual measurements 2. Show bounce after with actual measurements 3. Explain instructions 4. Review build quality/longevity Instead you eyeball everything and seem confused by basic instructions.
