This Bluetooth mouse provides a very comfortable experience for interfacing with your computer, including an extra-smooth scroll wheel. Simply pair the mouse with your Bluetooth-enabled computer, without needing a dedicated wireless USB receiver like many traditional wireless devices. The cleverly-designed mouse comes with a DPI switch which can instantly adjust sensitivity, and rubberized finishing provides superior grip and comfort. Thanks to the ergonomic design the mouse can be used for both right and left handed users.
