Standard Plus (with LP: Lubrication Pack)

Works great. I think it even makes the balls firmer than factory. It's allowed me to keep playing with the balls for weeks. Worth the cost if you play a lot and don't require new balls every time. I wish they sold long tubes for it.

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.

I’ve used these for a year. First of all, this works as advertised. I was able to repressurize a Penn can past the pressure of a new can and preserve & use the same tennis balls for a whole month. I already have a portable device I can use to add air to my car tires so this made it easy for me. I probably saved myself from buying some cans, because in some of my fun sessions we agreed my repressurized balls were just as good as a new can. But you need to make sure you regularly oil the O rings. I did not do that. After 15 uses, it reached a stage where I could not unscrew it (as a man with a right hand grip strength of ~105 pounds). Although months later when my arms weren’t sore I was eventually able to unscrew the stuck ones with a rubber grip at the bottom, sitting down. I used the silicone grease that came with this, after wiping both the o ring and where it sits with a lens wiper. Main tip. After around 10 uses, clean and oil. If you don’t have as good of a grip strength, drop that to 5 uses. Otherwise after you release the air and try to unscrew you will struggle (despite you being able to screw it in the first place).

For decades I used the classic yellow and white ball savers that hold pressure up to 14 psi. If that thing lost pressure you wouldn;t know and the balls were never really re-juvinated. The thing I like about this ball rescuer are: 1. Creates pressure up to 30 psi and holds the pressure for a very long time. Had it for a week and still no loss of pressure. 2. Easy to tell if it loses pressure and can be topped off or fixed with cleaning and lubricating the o-ring just like other ball savers. The way the mechanism works its much easier to keep dust and debris away from the part that needs to hold pressure. 3. Re-uses cans. I use Penn balls and the Penn cans work great with this.

great product, saved me a lot of balls, great invesment.

Suelo jugar con 4 pelotas y no conseguí envases de 4 pelotas que encajaran de manera correcta en estos presurizadores, así que decidí usar 2 de cualquier marca para adaptarlo, use uno de marca Wilson y otro marca Yonex, ambos de 4 pelotas, lo único que hice fue calentar ambos lo suficiente en la parte superior con una pistola de calor y despues de unos pocos minutos al estar un poco blando el plástico lo presione con el presurizador y tomo la forma exacta encajando de manera formidable, ya he adaptado varias marcas, recomiendo hacerlo si el envase que les gusta no se ajusta al cierre del presurizador, dejo un par de videos para mostrar el resultado. Nota adicional, probando otros envases me di cuenta que el tubo de pelota de marca "Dunlop Fort clay court" de 4 pelotas y cuyo envase es de metal, encaja perfectamente y mantiene la presión desde principio a fin, el único detalle es que no es transparente asi que no se puede observar la condición de las pelotas, es bueno recordar que a lo largo del uso perderá la capacidad de poder recuperar la presión y si se carga con los 30 PSI las pelotas pueden hundirse si ya están muy blandas.

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.
