The Cherry MW 9100 USB wireless mouse has a compact design that nestles right into your hand. The mouse has 3 different resolution levels and using the handy DPI button, you can easily switch between 1000, 1600 and 2400 dpi. The MW 9100 can be connected to your device using Bluetooth or the 2.4GHz radio receiver. Using the slide switch on the bottom of the wireless mouse, you can easily change between either connection mode. In both cases, the transmission is carried out using AES-128 encryption. One charge of the lithium-ion battery lasts several weeks, but when the battery is low, the mouse charges conveniently via the included USB-C cable while you continue working.
