Unimouse is has a vertical shape so the hand sits in a handshake position. The adjustable thumb rest and tilt (ranging from 35 to 70 degrees) lets you customize it to feel as natural as possible.
Rollermouse, on the other hand (pun intended), is a total redesign. This mouse sits in front of the keyboard to encourage better posture and body alignment. We tried it and were impressed with its speed, and how it adjusted to our movements—which is the work of built-in tracking technology.
By integrating either device into your work space, you can help make yourself feel better—which sounds pretty smart to us.
