BALL RESCUERTennis 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.

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.

This product is excellent for maintaining the pressure of new balls. Does exactly what it is supposed to do. However, it does not add pressure back into already-flat balls. I assumed it would, but it doesn't, and can't. The reason is that when you put a flat ball in, and pressurize the can, the flat ball will squish--actually dent--until the pressure inside the ball is the same as the pressure in the can. If the ball were rigid, then air would go into the ball, but the ball of course isn't rigid so higher pressure air outside the ball just squishes it. Oh well. It's still quite useful to have it maintain the pressure of the balls.Note that you need a Penn or Dunlop ball can. Wilson and Babolat ball cans don't fit.

This only fits with some tennis ball canisters. It works fine with the ones it fits, but it’s a bit annoying to have to go out of our way to find tennis balls that specifically have the right size canister based on the manufacturing country. For the price, I would probably prefer to just purchase the full canister-sized pressure savers instead.

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.

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

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.

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.
