This is the best wireless mouse money can buy at the time of writing this review, I mainly play fps and Iv noticed a a big improvement in micro movements e.g aiming down sights and long range sniping. Been using for 4 weeks 8/8 Would buy again

The Razer Viper Ultimate is a solid choice for anyone looking to beef up their arsenal of wireless mice. It's reliable, sturdy, and a step above its previous models, with plenty of style to boot.

Light yet sturdy, Phenomenal 20K CPI sensor, Battery lasts and lasts

Exorbitantly priced, Fewer customization options

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 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

The Razer Viper Ultimate offers up some premium tech packed into a featherlight, ultra-responsive chassis, and the result can often be a stunningly intuitive experience.

Impressively lightweight, Lightning fast click response and tracking, Subtle design

Expensive, Small number of programmable macro buttons, No option to add weight

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.

For the past few months, impressive and exciting gaming mice have continuously popped out on the market. And with how it’s going, it looks like a race to push boundaries and innovate, making things fiercer than ever.

If you do want an accurate, sensitive wireless mouse with stylish charging and flawless performance then, sure, the Razer Viper Ultimate is a worthwhile investment. However, rivals like the Corsair offer fantastic core performance for a lot less if you’re willing to forego wireless functionality and...

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.

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