◇Razer Basilisk Ultimate Gaming Mouse - High-Speed Wireless, 11 Buttons, Tilt Switch, Focus+ Sensor, 20000 DPI, Charging Stand, Chroma - Black (RZ01-03170100-R3A1) Used for about a year. There are some minor stains and scratches, but it works without any problems. I don't smoke. I have cleaned it simply, but as you can see in the photos, please refrain from purchasing if you are concerned about the condition. The box has a dent.
