Review

The BIGTrack roller ball was originally intended for children's use. Both ball and buttons (left and right click) are large enough to be controlled by feet or elbows, making it ideal for use by anyone with poor motor control.

It comes in two versions, one with switch inputs at the back which allow you to replace the buttons with switches of your choice (the switches are sold separately).

This roller ball is less helpful for people with severe learning disabilities as the buttons are both blue, making it hard to differentiate between them. The ball is also too large for some people to access comfortably.
