This is one of the better trackball loved by the trackball users community.

Featuring large ball, and 4 large buttons.

Ball Size

Ball diameter: 55 mm. This is same size as Kensington Expert Mouse.

The 2 buttons on the north side are harder to reach. The bottom left is the easiest to press, with thumb. (if you use it with right hand.)

Twist Earth to Scroll

The Slimblade also features a twist scroll wheel. You twist the ball to scroll, like rotating earth. It's awkward. Not very good in comparison to a scroll ring or scroll wheel.
