I used this for about a year and then put it away. I only used it indoors, so I don't think there are any noticeable scratches. I have confirmed that it works. I am also selling this on other platforms, so I may have to cancel your order depending on the timing. I apologize for any inconvenience. --------------- Logitech Wireless Trackball MX ERGO MXTB1s (Black) Brand: logicool Mouse/Trackball Type: Trackball Cable Type: Wireless Number of Buttons: 8 buttons Optical Resolution (dpi): 2048 dpi Mouse/Trackball Features: Tilt Wheel, DPI Switching, Rechargeable Color: Black, Gray Weight (g): 164 g Battery Type: Proprietary Battery
