This device has definitely helped my carpal tunnel symptoms. I think it would be nice to use it as a massage tool AND have something with which to cover it to use for longer term use as a wrist positioner with the mouse. It isn't really helpful to rest ones wrist for very long as you just get impressions from the rubber all over your wrist. The intended use of rolling your wrist back and forth on it for exercise and alleviation of symptoms is VERY well designed. I am glad to have it and would purchase another for someone with the same problems.
