Description: The mechanical movement of the original mouse will not display anything on your PC. The turntable turns back and forth, occasionally stopping for a few seconds. The bottom is supported by a number of silicone pads to prevent slipping and prevent vibration transfer to the table. There are 7 different color LED lights to choose from, and the light can be turned off and on. With memory function, it will light up the previous color. This specially designed mouse micro actuator is a nice companion for home workers. It simulates mouse movement and prevents the computer from falling asleep when you work or play. This mouse shaker is compatible with all operating systems.
