Our Verdict

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

Holding the Razer Viper Ultimate for the first time, it’s difficult to comprehend how such performance can be so featherlight. At first glance, Razer’s ambidextrous esports mouse could be mistaken for cheap it’s so lightweight, but don’t be fooled - this isn’t your average pointer. Much like the standard Razer Viper or the smaller Razer Viper Mini, the tech packed inside such a streamlined shell makes for blitzing speed and accuracy. It's potentially the best wireless gaming mouse we've seen in the last year or so.

Its panel is also a standout feature for several reasons. First of which is that it's a non-glare screen and one that genuinely does succeed at being so. It's also blisteringly fast, with the screen on our review unit boasting a 240Hz refresh rate. This pace on a 1080p panel on a powerful gaming laptop has 'excellence in shooters' written all over it. Particularly when MSI alleges that the screen can get close to 100% sRGB too. If the colors can be of that degree, then flying around shooters at that pace on-screen will be a thing of beauty.

Complementing the visuals are audio features. The GE66 Raider's speakers are pretty decent and some work has gone into making them stand out. The Duo Wave Speakers are of a new design and offer generous sound for a laptop - though 'for a laptop' is doing a lot of work there, as the audio is weak, and you'll still be way better off with one of the best PC headsets for gaming. 

In terms of connectivity and ports, you can see it's a solid offering, particularly when there are two USB-C ports going, and the HDMI supports 4K at 60fps (allegedly).


An unassuming aesthetic and slimline profile make the Viper Ultimate sit perfectly on any desk. There’s no glaring LEDs poking out of every corner, but a simple matte finish over the classic Razer logo makes a satisfying statement nonetheless.

This matte covering evades prints nicely, with a textured grip down each side keeping everything under your control to create an incredibly tight experience overall. In other words, it's pretty much the same as the standard Viper (a contender for best gaming mouse when it comes to first-person shooters).

If you’re looking for a mouse conducive to a lighter touch fingertip grip, the smaller profile and squat design makes the Viper Ultimate a seamless extension of yourself. If, however, you prefer a heavier claw design, you might struggle to gain purchase on the skinnier frame, especially with larger hands. If you’re looking for a gaming mouse designed to fit directly into an esports player’s hand, however, you’ll be after this lighter form factor anyway. 


The Razer Viper Ultimate may be light and sleek but it’s certainly not lacking in sheer power. Inside this nimble exterior sits some serious tech, with Razer’s optical sensors and switches working to deliver an effortless scan across the battlefield that still keeps up with twitch reflex clicks. 

The effect is just as noticeable in everyday work, and after a week’s continuous use in both work and play, switching from the larger Logitech G502 Hero to the Razer’s nimble form makes every pinpoint movement feel even fresher.

Speed, of course, isn’t everything. Rest assured however, the responsiveness of the Viper Ultimate doesn’t come at a detriment to its precision. Even the newest of PC gamers will appreciate the smooth tracking and astonishingly low latency. 

It’s not just fast for a wireless mouse either, spinning backwards to deliver a panicked headshot to an attacking Raptidon in The Outer Worlds, the Viper Ultimate served up a speed and accuracy that many a premium wired mouse would be proud of.

Overall - should you buy it?

The Razer Viper Ultimate gives a platter of premium tech, yet it still manages to present all that in a featherlight, ultra-responsive chassis. The result is impressive. 

That’s if you’re willing to pay, however. This pointer certainly doesn’t come cheap, especially considering the limited customization options in both programmable macro buttons and weight.
