The autostart system is excellent. I use it to warm my wrists for 30 minutes by car to the ice rink, and after the games I still have feedback on my way home with a powerball. Wrist pains disappeared with this "rite". I play with the 95flex racket, which is already some kind of impact load on the wrists in shots
