Logitech 910-001105 MX Wireless Performance Mouse Black with Box Pre-owned itemThe woman I bought this from said it works fine. She didn't use it for long because it was too big for her hand & was uncomfortable for her. It shows very little wear. Noted issues are that the bag exterior has some crackles & the wall plug/cord is missing. It still can be used because it has the USB cable. I didn't download the software but I plugged it into my laptop & it appeared to be charging
