It features a touch-ring for scroll, but many don't like the touch-ring. It doesn't scroll reliably, and when you are using the ball, it's easy to touch the ring by mistake.
This trackball is small, same size as a small mouse.
The buttons are on the sides. To press them, you have to actually hold the thing.
Ball diameter: 32 mm.
