Razer Viper

A strong, ambidextrous design ; Extraordinary polling rate ; Very lightweight

Expensive for an esports mouse ; Hyperpolling works better with higher-end PCs, so performance may vary

The Razer Viper 8K promises the fastest data transfers you'll see in an esports mouse—if your PC contains powerful enough components.

Comfortable for a low-profile mouse. Optical/mechanical switches increase durability. Anti-drag cord allows for smooth movement.

Expensive for an esports mouse.

Bottom Line: The comfortable, light, and quick Razer Viper refines the company's esports offerings with an excellent gaming mouse.

Excellent performance ; Comfortable ambidextrous design ; Lightweight ; 8K polling rate, 20K DPI

Weight isn't adjustable ; Symmetrical design won't be for everyone ; Unintuitive DPI button placement

With the Viper 8K, Razer improves upon the original in small, but meaningful ways while keeping the price the same.

Ambidextrous, comfortable ; Rubbery grip material makes it easy to grip ; Intelligent, accurate sensor ; 8000Hz polling rate, but has 2000Hz and 4000Hz options too ; Lightweight ; Excellent cable, feet, and buttons design

Requires a beefy PC & high refresh rate monitors to utilise its full potential ; Not enough RGBs?

Apart from the top-end 8000Hz polling rate, Razer has also added their latest, top-notch components into this excellent, esport-worthy gaming mouse

Speedy optical switches ; Super lightweight 69g frame ; Exceptionally smooth glide ; 16K DPI and 5G sensor ; Comfortable

Design won't be to everyone's taste ; DPI button's hard to reach during use

The look of Razer's new esports mouse may not be to everyone's tastes, but you can't argue with its performance.

Mouse movements can look smoother on screen ; Ambidextrous ; Many programmable buttons ; No 8,000 Hz price premium

High polling rate can be inconsistent ; Adaptive-Sync should be turned off ; Half of the 4 side buttons are hard to use ; Not great for palm grips

The Razer Viper 8K Hz shows what an 8,000 Hz polling rate can do to improve the tracking of fast mouse movements if you have a powerful enough setup. But the Razer Viper series has its own design flaws, like some inconveniently placed side buttons.

Solid performance ; Razer Speedflex cable ; Doesn’t hinder left-handed players

Half the side buttons are hard to use ; No standout features ; Too small for most palm grippers

The Razer Viper is a middling gaming mouse with solid technology undermined by its build, which specifically targets claw and fingertip grips but not the common palm grip. Still, it’s among the best options for left-handed players.

Stylish.

Expensive.

If you’re serious about your gaming the Razer Viper is a mouse you definitely want to get your hands on. With almost no faults, an excellent sensor and lightweight body, the Viper is a fantastic mouse that is definitely worth buying.
