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.)
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.
Work in Linux?
Yes. Works in Linux out of the box.
- Lower left button is left click.
- Lower right button is right click.
