My new gaming mouse is now $20 cheaper in the October Prime Day sale than when I bought it last month
The Viper Ultimate has fallen off our list of the best gaming mice, but only because it's a few years old now and there's newer stuff. We rated it an 89% back in our 2019 Razer Viper Ultimate review and said "it's light, ambidextrous, feels good in the hand, and tracks your movements as well as a wired unit."
