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.

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!

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

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 is an outstanding mouse for sure. It is lightweight and the connection feels just like a wired mouse. However, Razer has some quality control issues, especially with this mouse. I am on my 3rd RMA. The switches are just horribly inconsistent. It either creaks a lot or it feels "sticky" and less snappy. Only buy this mouse if you're feeling lucky.

Got it and used it for work and everything seemed perfect. Then finally got some time to use it for a 3rd person shooter game. That's when I noticed the right mouse button(right click) sometimes fails to register. Shooting games uses a lot of right click that's the default button for scope . Searched online if it's a known issue, I did find mentions of issues with right click but not quite similar with mine

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

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

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.

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...
