Rapoo Wireless Optical Mouse 1090p

So small and unobtrusive that you can easily forget it after plugging it into a USB port; and what you don't disconnect, you can't lose.

With Rapoo's latest energy-saving technologies, you can use the mouse for up to 9 months without changing the batteries.

The 5.8 GHz wireless connection operates far away from the 2.4 GHz frequency band, which is shared by wireless, Bluetooth, and Wi-Fi devices with other applications.
