Lightweight, high-precision wireless gaming mouse with charging dock. - Model Name: Viper Ultimate - Color: White - Type: Wireless Gaming Mouse - Accessories: Charging Dock - Cable: USB-C Cable I've used it for about a year since I bought it. There are no noticeable stains. Operation has been confirmed. It's been about four years since it was released, but I think it's one of the mice that can be used very effectively in games like Valorant.
