Superb textured side grips ; Agile design with slick feet ; Ambidextrous design ; Excellent battery life

Side buttons are a bit too recessed for easy access ; Lacks the RGB lighting of other mice

Sure, it's not cheap, but if you want a seriously awesome wireless mouse then you'll often have to pay a premium. And in the Viper Ultimate, you're getting what you're paying for. Once bitten you'll be smitten.

Long battery life ; Incredibly responsive sensor and buttons ; Lightweight and compact ; Ambidextrous

Can be uncomfortable for larger hands ; Accidental side button clicks when not using a claw grip ; CPI controls aren’t readily accessible during gameplay

Razer’s understated Viper Ultimate packs impressive tech and performance, but its small form factor and light weight make it best-suited for claw grip gamers.

Comfortable ambidextrous design. No-compromise RF wireless connection. Wireless charging is convenient and looks sharp.

A bit expensive for the full package.

Bottom Line: Razer's Viper Ultimate untethers and upgrades one of the best gaming mice a competitive esports player could ask for. It's a winner, but get the version with the charging dock.

Top-of-the-line sensor ; Great feel-factor

HyperSpeed feels a bit ephemeral ; Quite expensive for a single piece of kit

Great, consistent wireless performance Huge sensitivity and accuracy levels Neat charging dock Sleek, sturdy, lightweight design

No-one needs 20,000 DPI Far pricier than rivals Misses out on some features and buttons

Our Razer Viper Ultimate review reveals that there’s a lot to like about this mouse. Its core gaming performance is great. The main buttons are fast and responsive and the whole mouse is accurate and precise.

Granted, not everyone is willing to drop $150 on a gaming mouse — even a high-end wireless one. In that case, the wired Viper is probably a better investment, at $80. But if you can make the splurge, the Viper Ultimate is almost as good as these things...

20K CPI sensor is the best we’ve seen ; Light in the hand, with a grippy finish ; Ambidextrous ; Long battery life

Expensive ($150/£150) ; Right and left clicks feel a touch flimsy ; Fewer programmable buttons than competitors

Razer’s new Focus+ Optical Sensor puts the Viper Elite at the top of the wireless pile. Some of its buttons fail to live up to its hefty price tag, but its long battery life and elegant, ambidextrous design more than make up for it.

Response was good

It was a bit too small for my hand, i use a claw grip and overtime my hand will tense up

Wireless, build quality, accurate sensor

Too heavy for me and big. I am a large hand size but still feels massive. Maybe I need a fast gamepad with it idk
