Trackball mice are an acquired taste, but the MX Ergo’s innovative design may have wider appeal. Folks with extra-large hands might find it a little small, but for most it will be a welcome addition to their gear bag. We also like that there is no USB receiver to worry about misplacing-the Arc Mouse connects via Bluetooth 4.0. It uses a single click pad for left and right buttons and scrolling, and the default settings can be changed in Windows device settings.Īt just 5.17 x 2.17 x 0.56 inches, the Arc Mouse is easily the most portable mouse we tested.
It lays flat until you bend it into an arc that conforms to the shape of your mouse-ing hand. If we had a “most unusual mouse design” category, the Arc Mouse would win that as well.
