The Mousetrapper Advance is a Swedish anti-RSI peripheral which is attached to the keyboard to replace mouse functionality and save your fingers. Once installed all navigation is done using the ergonomically located roller square and 5 large programmable buttons. It looks like an interesting idea all round. £169.95.

 Mousetrapper Advance is placed in front of the keyboard, i.e. between yourself and the keyboard, in order to gain support for your wrists and to easily reach the steering pad with your fingers. Placement and design enables both left and right handed individuals to comfortably manoeuvre the Mousetrapper.
