For sale: Microsoft Mouse Bluetooth Wireless 3600. I used this mouse for about six months, but haven't been using it recently, so I'm offering it to someone who needs it. Operation has been confirmed on Windows 11. It's compact and designed for either hand, and runs on a single AA battery. The color is a semi-matte black. I used it almost every day for about six months, so there are some minor scratches on the exterior, and the matte material on the sides shows some slight discoloration. Despite the minor scratches, there are no operational issues such as malfunctioning clicks or scrolling, and I think it's still perfectly usable. I've confirmed its operation, but please consider it as a used item before purchasing. Please feel free to ask any questions you may have(^^) Power source: Battery-powered Connectivity: Wireless (Bluetooth)
