Contour Design Continues to Perfect its Novel Roller Mouse

Contour Design's 3rd iteration of its Roller Mouse has arrived. It looks like a fancy add-on keyboard wrist rest. A device worthy of The Golden Child, you roll it like a paint roller for up and down motion. The rubberized touch portion of the roller can slide freely from left to several inches along the inner axle rod. The software is set to hop the mouse to the edge of the screen when you reach the edge of axle. The buttons are located in middle at the thumb position of the wrist rest. The standard version has 3 buttons, the pro version 5 and the brand new 'free' version also has 5 but they aren't adjustable like the Pro. All the models come with a regular scroll wheel.

The first two larger models look large and blocky next to the Free. If a large wrist area is what you are looking for though the Free comes with snap-in wrist pads extending it to a similar size as the previous versions. If they turned out a keyboard version where the bar was at the top of the keyboard (with no F-key row) it might justify the high price tag of $219. At that price for the roller mouse alone they are might have to teach it a few more tricks.
