Sigma A.P.O presents to us, the Sigma ONYX SLATLRF1 Wireless Laser Mouse. The ONYX SLATLRF1 laser mouse uses a 2.4GHz frequency to connect wireless and features 5-buttons (not sure if they are customizable) and a 21mm long USB dongle.
The ONYX Wireless Mouse also has a smart standby mode which conserves the power and in return giving it a longer battery life. It is presently available in the colors of Bronze, Violet and Black with a price tag of 7,980 Yen which is approximately $83 US.
