Good ergonomic mouse, 28 Jan. 2014
The Contour Free2 Rollermouse has already made a huge difference to my life. I had been getting persistent pains in my shoulder from the use of a normal mouse, but with the new rollermouse, which sits in front of the keyboard, I don't have to reach out to the side any more, and the pain has died down within a few days. The mouse takes very little getting used to. You can adjust several aspects of the rollermouse, including its positioning and its depth relative to the keyboard, and also the cursor speed (how far or fast the cursor moves across the screen as you move the roll bar). The only drawback I've found is for gaming. The rollermouse is best used with two hands, which isn't so good when gaming on a PC on games which simultaneously require one hand for the mouse and one hand for keyboard controls. However, it is in principle possible to use the rollermouse with one hand, so it might just be a question of practice!
