I don't usually feel the need to write reviews, but after having such a bad experience with these balls i'd hate to thInk someone would waste there money buying them. I'm a regular club player and was recently playing another club in a local league. We opened a couple of tubes for the fixture and both sets had zero bounce straight from the can. Granted it was a relatively cold day (5degC), but these balls just wouldn't carry for baseline rally's especially if you hit with a little top. On a positive note, they make you watch the ball as the bouce is so alien and to be fair... the wear rate was ok as after 4sets on a hard court the balls didn't fur up. But my preference would be to buy a set of slazenger or dunlops and enjoy your tennis with a ball that bounces.
