The actual discount might only be a humble £3, but this makes the Viper Ultimate the lowest price it’s been. For that price you get an optical sensor with 20,000 Dpi and the RGB Razer logo on the mouse, both of which can be customised using Razer’s software. The Viper Ultimate is really easy to use thanks to it weighing only 74g, and it’s truly ambidextrous with side buttons on both sides of the mouse. The biggest draw is that it’s wireless, so no need for cables, or buying batteries as it can go up to 70 hours without needing to be placed in the charging dock. The main difference between this mouse and the newer Viper V2 Pro is that the V2 is lighter at 58g, newer switches, and a longer battery life. It doesn’t have the side buttons on both sides though so is less ambidextrous, and it will cost you £149 right now.
