This mouse has to be one of the best mice I have ever tried throughout my gaming years, very few have withstood my expectations in a competitive level and this being similar to my previous mouse, the Razer abyssus in it's style made the transition even smoother than I expected. The viper ultimate is slick, responsive and I would have to say a must for anyone who is even remotely interested, I will be using this for many years to come like my previous mouse and it'll serve me in both casual and competitive fields. 10 out of 10.

I bought this mouse about a week ago and I came from the Logitech G502. The first change of shape and weight was hard to adapt especially in the first few days but after some decent use, it feels a part of your body. The sensor is spot-on with this mouse and it has not yet tripped with any inconsistencies on the mouse mat. The clicks were hard to get used to but once you do, you would find it easy to click exactly when you want it to and not click too early or mis-click; this is important as I am an FPS player myself. The scroll wheel feels strange at first but once you adapt, it will feel great – especially when scrolling down for those bhops. The side buttons feel great although it seems too shallow for me, I will let it pass it is an ambidextrous mouse and I assume it would prevent mis-clicks. The overall shape feels weird at first although it pushes my fingers into a claw grip, allowing faster click times. I personally use this mouse with the charging dock and occasionally it would

It's good, I recommend it

Been a fan of Razer for a long time and for a good reason. No other companies can match Razer in terms of quality mouses.

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

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.

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...

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...
