Traxsys were previously known as Penny & Giles.
A good rollerball with a guard to reduce accidental button-pressing and a long-standing reputation.

Very sturdy rollerball with bright colour-coded buttons to help pupils who struggle with the concept of left and right mouse buttons.

This requires very accurate control, but can be ideal for some pupils with restricted movement.
A really large ball but can be quite difficult to grip and is too lightweight.
Also it’s no longer manufactured so getting hold of one can be rather difficult!
