xwing,
I love mine and would not bowl without it. The premise is that the little ball bearing pushes on a pressure point in your wrist and can take as much as 10% of the pressure off your wrist. Thus calling it F10X I would assume. Anyway, I had some hand pain a while back and put one of these on and have never had a problem since. I also know several others who swear by them as well. In fact, we recommended them to some ladies who are secretaries and they even helped their carpal tunnel, however you spell that

Who needs a 300 or 800, when I have a 294 and a 295!?!?!Edited on 10/4/2004 2:31 PM
