This is a gently used (one year) Razer Viper Ultimate Hyperspeed Lightweight Wireless Gaming Mouse, in classic black with RGB charging dock. I purchased from Amazon as a factory renewed item--still in perfect condition. Comes in Razer brown box packaging with retail user manual, a quality braided usb cord, and convenient RGB charging dock. Much reviewed and highly rated mouse--only selling because I have too many gaming mice on hand and have other old favorites. See pics and below for specs and more detail.
