The Logitech MX Master Mouse delivers accurate cursor controls wirelessly by featuring a laser sensor and connecting via 2.4 GHz frequencies or Bluetooth technology. The Darkfield laser sensor can be set between 400 to 1600 dpi for custom controls while gaming. The mouse can connect wirelessly to Bluetooth-enabled devices, such as tablets and notebooks, and a USB receiver is included for non-Bluetooth systems. On the exterior, the mouse sports a scroll wheel along with left and right mouse buttons as well as back and forward buttons. Additionally, powering the mouse is accomplished via a 500 mAh LiPo battery, which has a battery life of 40 days and can recharged for up to 2 hours use with a 1-minute fast charge. To help preserve power, an on/off switch is on board.
