Penn Championship High Altitude Tennis Balls - Extra Duty Felt Pressurized Tennis Balls, 12 Can, 36 Balls

Nice balls to play with

Great product

The seller slapped a high altitude sticker on the outside of the box but don’t be fooled! These are extra duty balls as marked on the outside of box printed by Penn and also marked on each can. SCAM

I'll be honest—these Penn Championship tennis balls really don't hold up well for matches. The lifespan is short, and they lose their bounce pretty quickly, which can get frustrating. I prefer using other brands when I'm competing. However, for practice with our tennis ball machine, these work just fine. The big plus is that they recharge fairly well in our tennis ball repressurizer, so we can extend their usability. And at less than $30 for a 12-pack, they're definitely worth it for practice and training purposes. Just don't expect them to last for serious games.

The product is a standard one and equally durable. We love using it and will continue to use them.

These balls hold up well under normal use. Might get 4-6 sets out of them before they start to deaden.

After a little research, I discovered that High Altitude Tennis Balls have less pressure and are 6% bigger than standard tennis balls. I live at over 6,000 feet and find that the high altitude balls compensate for the added speed and bounce the we experience up here with standard balls.

It doesn’t say it anywhere on the box! Guess I’ll have to open to confirm the type of ball. As I need high altitude for my use.

Publican que son pelotas de alta-altitud, pero son los normales. No dan la opción para devolución.
