Reviewers Liked

  • Thin enough to stick in a shirt pocket. Seamlessly switches from mouse to a 360 degree trackball. Autosleep mode automatically extends the two AA battery life up six months. Seriously. Plastic chassis feels like metal with some heft. Amazingly comfortable
  • The mouse fits nicely in the user’s palm; excellent battery life with built-in gauge; multiple modes - trackball and traditional mouse; trackball feels more speedy and precise than a scroll wheel; sleek good looks

Reviewers Didn't Like

  • Mouse/trackball mode button initially takes some time to figure out. Hard to know when sleepmode has kicked in
  • No included dongle for non-Bluetooth laptops or desktops
