I bought this for work, but it didn't fit the depth and size of my office desk, so I'm selling it since I bought a different one. I connected it to a laptop once and used it for about an hour, but I've kept it in the box since then. There are no signs of use, so I think it's practically new. This is a Bluetooth 5.0 compatible mouse from BUFFALO's NEOFIT series, known for its comfortable fit. - Brand: BUFFALO - Model Name: NEOFIT - Connectivity: Bluetooth 5.0 - Features: 3 points of fit - Battery Type: AA Battery - Intended Use: PC Peripherals
