As we know， the optical mouse is a computer pointing peripheral that uses a laser eye instead of a rolling ball to move a cursor around the screen. The retractable optical mouse has become our highly recommended product for its compact design and good performance. The optical mouse with a retractable cord is a portable solution if you use your mouse with different computers or with a laptop. It is able to work on almost many surfaces， including those that are not entirely flat. The ventilation design on both sides allows the mouse to breath freely， preventing overheating. The ergonomic mouse is designed to use the precision movements of the hand. Nowadays， the older mouse is out of date， and the latest gadget is your best choice.
