BEST PORTABLE WIRELESS MOUSE: MICROSOFT ARC MOUSE
If we had a “most unusual mouse design” category, the Arc Mouse would win that as well. It lays flat until you bend it into an arc that conforms to the shape of your mousing hand. It uses a single click pad for left and right buttons and scrolling, and the default settings can be changed in Windows device settings. At just 5.17 x 2.17 x 0.56 inches, the Arc Mouse is easily the most portable mouse we tested. We also like that there is no USB receiver to worry about misplacing—the Arc Mouse connects via Bluetooth 4.0. Folks with extra-large hands might find it a little small, but for most it will be a welcome addition to their gear bag.
