Review
The different TRAC and KidTRAC roller balls are based around a single design. They all have three buttons, left click, right click and drag lock, and on the KidTRAC versions the buttons and ball are different colours, making them easy to use if you find it hard to remember left and right.
The buttons do not have a guard, so you are more likely to move the pointer off target if you jog the ball.
KidTRAC rollers have coloured buttons and are available with PS2 or USB connectors. They are also available with switch inputs, allowing you to replace the buttons with switches (which are sold separately).
TRAC rollers are aimed more at adults, and are available in grey or black, and with USB or PS2 connectors
