Tennis Ball Pressurizer – Converts Compatible Tennis Ball Container into a 30 psi Ball Pressurizer & Extends Ball Life (Pump & Container not Included in Standard and Standard Plus)

Easy to use. Works great. It's so nice to play with fully pressurized balls every time. I bought one 3 years ago. I bought a second one so I will always have six balls ready to play with. It pays for itself by prolonging the life of your tennis balls. I use the same balls several times. I only open a new can when I want clean balls because the good bounce is maintained. NOTE: Only use silicone lube to lubricate the O-rings and exhaust seal. Do Not use vasoline because it will slowly deteriorate the rubber.

Overall a good product. It seemed to be complicated to use at first but it actually is a lot easier than it looks. It does revive balls that have been used moderately (not intended to revive old, dead balls, but for preserving the life of new balls, it works well). Try to make sure to maintain this product by lubricating so pressure doesn't escape, and troubleshoot by using a wrench if the device gets stuck on the can.

Overall, I’m happy with it and it does work much better than the Gexco and Tourna twist style ball savers. Using a bike pump gives you a lot of control over the amount of pressure.Couple of tips:1. It is VERY finicky about the can because it relies on having a regular Penn Championship can with a perfect metal rim. You may need to try many cans before you find one that holds pressure. Dents and cans that are out of round will cause leaks.2. You can use this to repressurize completely dead balls but if you use too much pressure and the ball collapses it will never gain pressure. You have to take your time and pressurize until just before it collapses and leave it there for a week. Then add a little pressure and leave it there for a week etc.

Works very well if you use the right compatible container. It seemed to be complicated to use at first but it actually is a lot easier than it looks. It does revive used balls and keeps them with the right pressure.

Ball Rescuer at 32lb PSI kept my US Open and Dunlop tennis balls bouncing like new until I could no longer read the print on the ball. I play 3-4 times a week and kept balls like new for over 2 months. Ball Rescuer really works! Love this product … and with an electronic battery powered pump it is so easy to use. Customer Service was so good too, they promptly sent me a lost O-ring no charge when I accidentally lost it. Many Kudos to Ball Rescuer USA.

4/23/2024 My unit leaks, after some experimentation think I have found a solution. You need to fill in the space where the unit joins the threads. I used a silicone to fill the joint. Keep in mind that just gluing the joins together may not or may not work. In my case I put the unit together and tighten it. There was still some space between the joints. I filled in that space with silicone. Make sure it is well lubricated so that you don't glue the cover portion to the bottom section. the lower rating is because I have not found that it repressurizes the balls, but it does keep the ball pressure up so you an use them longer.5/2/2023 I have tried the recommended Penn and Dunlop plastic cans and even Gamma, they are too large for the Ball Rescuer. 5/4 Update, opened up another Penn Championship can just to test again. This time the can fit. Will see how it performs.

I followed the instruction but its still slowly leaking air and would not hold pressure.

Muy bueno mantiene bien la presión de las bolas de tenis. De pronto cuesta un poco consegir el tarro apropiado.
