Whether you work in the office or at home, the Primo optical wireless mouse lets you control the laptop or PC with ease. Select your optimal speed with the speed selection button (1000-1600 dpi) and work wirelessly within an 8 m radius with the stowable USB micro receiver. Simply plug the small receiver into your laptop or PC to start... using the mouse immediately. When you're done, you can either leave the receiver on the PC or laptop, or store it back in the corresponding compartment in the mouse. To save battery power, simply switch the mouse on and off using the power switch. Whether you are left- or right-handed, anyone can use a wireless mouse and enjoy a wireless workspace!
