Contour's "legacy" RollerMouse is good for tight budgets, messy environments, and low work surfaces. Customers with more conventional needs may wish to check out the newer RollerMouse Re:d instead.
- More affordable than other RollerMouse models.
- Extra-thick palm rest is more suitable than other RollerMouse models for some low work surfaces, such as keyboard trays mounted below elbow height. In these situations, a thin palm rest can result in undesirable wrist extension, causing or exacerbating wrist-related issues.
- Enclosed RollerBar resists crumbs, dust, and other performance-reducing junk. (Note: The RollerMouse Re:d now features a sealed RollerBar, which has fewer dust problems than the Free without the plastic cover of the Pro.)
- Optional RollerWave accessory extends palm rest out further for more gradual slope and better support.
- Optional ErgoMat supports non-straight, non-flat keyboards such as the Goldtouch and Kinesis Freestyle.
- Unlike the Re:d and Free RollerMouse models, the Pro has a "clicky" scroll wheel rather than a smooth one.
- On large or multiple monitor setups, the Pro RollerBar tends to "run out of room" frequently. (Once again, this problem goes away with Contour RollerMouse Re:dRollerMouse Re:d[/link_product.)
