Any One Bought a Tennis Ball Re-Pressurizer?

[pretty cheap jewelry]

We are casual tennis players (ie once a week at most) although my kids have lessons sometimes.

I do not want to keep buying new tennis balls, and wonder if anyone has used one of those canisters that re-pressurize the balls.

They are available at the sports store, are not terribly expensive, but I would like to know if the balls are usable for at least a number of weeks before repressuring yet again.

Here is an example

I coach tennis. Unless you play only a few times a year balls will generally last 2 hours of play or 2 weeks, whichever comes first. If you want to play competitively against others, buy them by the case so you get the right "feel" when playing. If you are an occasional weekend warrior, then try the pressurizer.

I play tennis and have never thought of it. I do keep a stock of balls with me and they are the rather sturdy ones, so I don't I will be needing this one yet.
