Sure but you have to use it long enough for the stings to get loose. What percentage of tennis racket purchases are used more than once?

[franciscop]

A high one? All of the tennis rackets I've seen are used until they are torn, broken, and been repaired multiple times (at least the cords). True I'm from Spain, but it's rare that rackets are used only once.

You probably don't see the ones that aren't used. They're stuck in storage in people's houses.
