The Cherry MW 8C Advanced is a classically designed wireless mouse with an anodized aluminium surface and rubberized sides. The wireless mouse is precise even on 4K monitors. It has a four-stage, adjustable resolution and a high-precision sensor with laser LED that even works on glass. The generous lithium-ion battery (550 mAh) keeps you up and running for weeks on a single charge. The status LED not only indicates the battery and charging status, it also shows you the selected resolution and connection status. A switch on the bottom of the mouse lets you toggle back and forth between 2.4GHz wireless and Bluetooth. In both cases, data is transferred with AES-128 encryption.
