You roll the roller and slide it left/right to control the pointer.

The 3 big buttons are left click, middle click, right click.

The 2 strip buttons are copy, paste.

The tiny button in middle changes mouse speed. Below it is scroll wheel.

Wrist Pronation Problem

With this, you don't have to β€œmove hand off keyboard” anymore.

Depending on how much you type, moving hand off keyboard may be a good thing, because it provides your hand muscles a break.

One issue with this device is that you may get wrist pronation problem.

The difference between the pro2 and free2 is that the free2 has a open roller bar, and detacheable wrist pad, and more precision (dpi). It's also about $40 more expensive.
