This multi-mode mouse has a sleek contouring that emulates our premium ThinkPad X1 notebook. The slim design slides easily into a pocket and is great for traveling. A battery level indicator appears at power-on and a touch capacitive strip is used for scrolling. Its wireless USB dongle, charging port and connection switch is revealed when the top shell slides open. The mouse tracking sensor has a protective sliding lens cover integrated into its on / off power switch. When turned over, a built-in track-pad is automatically activated. This is designed to control presentation slides. Together, all these features create a unique, innovative mouse.
