Easy to spin. The hand surgeon recommended wrist for rehabilitation of tendon ruptures. Surprisingly tough.

Surprisingly good resistance when learning to exercise, strengthens the tennis elbow pain area well.

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

Works well for tennis elbow rehabilitation. The bearings started to make noise after a couple of months of use, but still work.

Great widget, as long as you get a grain of technology. Good training for the hands and strains the muscles that were not known to be😁

Effective inhibitor or rehabilitator of tendon sheath inflammation. Autostart is the winner when the wire cannot be broken. In active use.
