This has been on my smoke and pet free desk since the mid 2000s. I got a laptop and don't need this anymore. It was working fine and takes 2 AA batteries. Micro Innovations Wireless Optical Mouse # 0470 with the RF Receiver and the USB adaptor. It was working with Windows 11.

Yes my hand has worn off the finish. Yes the battery cover latch is broken off, but unless you pick up your mouse, it stays in place. It will work on a hard surface without the cover. Tou press the button on the Receiver, and when it starts blinking, you turn the mouse over, which will also be blinking, and use a pen to hit the small black button for the signal to sync. If you need parts, or just want a heavier smooth mouse to use, here it is. All the buttons function. Before you buy, please ask questions. I'm not a professional reseller, this stuff is from my personal collection or has found its way to me one way or another.
