The Computer Geeks sell a USB Powered Thermal Wrist Protector. It provides heat to the wrist which eases RSI pain and should make repetitive work more comfortable.
The best is of course to avoid RSI to begin with:
- Use the whole hand to grab the mouse. Holding the mouse with few fingers stresses the wrist.
- Reduce the speed and force of repetitive hand moves.
- Use keyboard shortcuts.
