Reviewed by George. Review Posted 29/11/2005

Expensive-so very expensive-BUT-so good, so very good. If you use a trackball, then this is one of the best, easy to configure, big ball makes for precise movements, keys are big enough to hit easily. Gave it a 4 for ease of use till you get used to having your wrist on the pad, and 4 for value-well it is expensive.

  • Overall 5*
  • Ease of use 4*
  • Value for money 4*
