it is a very simple mouse use. It is the belt that is connected to your PC by USB jack and it is the latter that feeds it. So, no battery needed for your wireless mouse and so no waiting charge. Obviously, out of his stack, your mouse no longer works. The carpet is not very large, but more than adequate because the mouse is very precise and does not require a large radius for operation. The mouse is quite small, you hold it between thumb and very aisémant ring and lets the middle and index fingers facilement.Elle also has a click wheel. The design of the mouse is nice but nothing extraordinary. In the end it is a mouse that I recommend for every PC user (especially mobile due to its small size) which are fed to recharge the batteries of their wireless mouse.
