It's the exact product i was looking for. Excelente pressure container, and ff for any chance (i.e. dust in the o-ring), there is a pressure loss, the pressurbox will automatically compensate it presurizing again the box.
Any other product I looked for, needed to be pressurized manually and weren't so hermetically sealed.
Excellent producto!!!

Easy and efficent. The best product to pressurize tennis ball and preserve them for long usage

Everything great so far after two weeks. Battery life seems ok (still on the first charge). Balls definitely keep their bounce in the Pressurebox much longer than without it.

Produit conforme aux attentes. Bonne conservation des balles

Tiene muy buena pinta y parece que rellena muy bien las bolas de aire

Its automatic pump really works and always keeps the proper pressure level, so it maintains new balls super well and revives used balls very efficiently.

its a lovely device worth buying I used it for the 1st time today the balls were better than a new can

Keeps my tennis balls like new so far after 2 weeks. Very happy with Pressure box.

Works as described. Costed a lot but well worth the investment .

Why the instructions are not in spanish?
I don't understand how pressurebox works because the instructions are not in spanish and I don't understand well english

Looks solid. Worked as advertised. Easy to charge and use. Hope it lasts

Good product and investment for long used

Pressurebox seems great quality and have had no problems with it to date.
Used on balls used 6-7 times at this stage. Seems to work as described. Will try new set shortly.

It works as expected and meets all my expectations. The only drawback is that the user manual says don't over tighten the cap. However, if I don't tighten it kind of hard, it would leak.

Espectacular

I will give a life extension to my tennis balls

Love this one! Extending ball life with a click of a button.

Excelente, hermoso, estético, moderno, facil, perfecto

Arrived exactly on schedule!

I did have a manual (pump type) ball saver. I loved it but it did loose presure over time and that's no good. The fact that this will keep the presure is a big difference. I've had it for only a few weeks but so far it's worth spending the extra on. If you have a group of players then all chip in and it will see you good.

Works great

not too loud, does not need to run very often in order to maintain pressure

Ensures I can use my balls a few sessions longer

Early days of testing and so far so good. Hopefully it will cut down on the turnover of balls.

Very good
