This Bluetooth mouse provides a very comfortable computing experience, complete with an ultra-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 6 buttons for easy surfing through web pages and/or large documents, as well as a DPI switch which can instantly adjust sensitivity. Thanks to its ergonomic design and comfortable wrist rest, you can work or study effortlessly for hours at the office or at home. The vertical layout brings your underarm and wrist into a natural position which relaxes the muscles in your hand, wrist and arm.
