TeckNetĀ® Z4 Wireless Optical Mouse Gamer, 2.4GHz 2000 DPI, Nano-receiver, 5 programmable controls, 5 user profiles (Personal Computers)
Handy mouse, even in office with these configurable buttons, I am fully satisfied. Also well tien battery charge, because I use rechargeable, so 1.2V instead of 1.5V required. I highly recommend, especially at this price point.
