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.

After using the Viper Ultimate in productivity work but also games such as Terminator: Resistance, Mass Effect Andromeda, Beyond Two Souls and Borderlands 3 we became really fond of it thanks to the flawless tracking, very good battery life and low weight.

The Razer Viper Ultimate did amazingly well in my testing. Getting a wireless mouse right is no easy task, but Razer more than managed to do it with the Viper Ultimate. The wireless functionality of the Viper Ultimate is peerless at this point in time: Battery life is even higher than Logitech's...

Excellent sensor performance, Peerless wireless functionality, Very solid build quality, Satisfying feedback from both the main and side buttons, Good scroll wheel, Lowest weight of any wireless mouse to date, Grippy coating, Great stock feet, Full software customizability, Well-done lighting

I don't like Synapse

Using the same shell as the Razer Viper (2019), making it wireless while making a few notable changes is what defines the Razer Viper Ultimate. It’s a great product overall – and I love the new scroll wheel. I think it’s a missed opportunity for the dock to not be a receiver.

Fantastic tactility and resistance on the scroll wheel rotation, Good wireless reception, no dropoff, Comes with removable SpeedFlex cable, Razer Synapse implementation with the dock is excellent, Still lightweight despite having a battery, Long-lasting battery life, Trophy-like stance while...

The wireless receiver dongle is a nuisance to be constantly plugged/unplugged from one PC to another, as the dock could’ve been another wireless receiver, “Proprietary” micro USB header, Hefty price premium for wireless functionality

The mouse uses great tech, but one size does not fit all. Razer Viper Ultimate Specs Design and Comfort Gaming Performance Wireless Performance Features and Software Battery Life Bottom Line

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

I really enjoy the mouse I bought it mainly for video games such Fortnite. And I am really happy I got it, although I didn’t like that you can’t take the thumb buttons out and it comes in my way but overall I love a lot good job Razer keep up the good work!

Compare to my Logitech and razer manga, the viper is much better. It is lighter and more accurate, suitable for both right hand and left hand user.

Razer Viper Ultimate Wireless Gaming Mouse is almost the perfect wireless mouse... very close indeed!
