Our Verdict
Razer Viper Ultimate
Razer DeathAdder V2 X HyperSpeed
The Razer Viper Ultimate and the Razer DeathAdder V2 X Hyperspeed are wireless gaming mice. The Viper Ultimate has an ambidextrous, low-profile design with two buttons on each side, making it suitable for left- or right-handed users. It has a rechargeable battery, and you can also use it with its paracord-like charging cable if you prefer. On the other hand, the DeathAdder V2 X has a more ergonomic, right-handed shape, and it supports Bluetooth. It's powered by an AA or an AAA disposable battery, and it has two CPI switching buttons on the edge of its left-click button.
