Review: Razer’s Viper V2 Pro Takes Gaming Mouse Performance to the Next Level

I get excited whenever Razer appends the term “Pro” to one of their devices because it means it’ll have the best, boundary-pushing technology and excel at a core performance aspect with zero compromises.

The latest product to receive the “Pro” treatment is the Viper V2 Pro, which builds upon the esports-focused design of the 2019 Viper Ultimate. With every change considered for this new mouse, Razer’s designers asked themselves “Is this made for the pro? Is this made for performance?”

Let’s take a closer look at the tweaks and upgrades offered by the Viper V2 Pro – one of the lightest and fastest wireless gaming mice available today – and why esports professionals like Marved from OpTic Gaming are raving about it.

A Single-Minded Ultimate Weapon


The new Viper V2 Pro was designed to do one thing: be the fastest wireless pointing device on the market.

It achieves this quickness by utilizing a combination of lightweight design, a 30K optical sensor, optical switches, and Hyperspeed wireless technology. At just 58 grams, the Viper V2 Pro is over 20% lighter than the Viper Ultimate, and the biggest benefit that I’ve felt from this improvement is my start-up speed — the time it takes between identifying a target and moving the aim reticle to it. The 70G acceleration and 750 IPS max speed (up from 50G and 650 IPS) also contribute to my new performance gains.

A reduction of 16 grams might not sound like a lot, but for how I grip the mouse and use my wrist for control, the difference feels like night and day. And this weight reduction was executed thoughtfully so the device still feels robust and premium. For example, the battery is lighter and more efficient, and delivers up to 80 hours of operation, which is a 10-hour improvement over the Viper Ultimate. The left and right key covers also use less materials and are more flexible for an improved feel.


There are a lot of these “invisible” optimizations that when paired with the new 30K optical sensor, deliver an advantage that’s deserving of the “Pro” designation. Now, if you’re thinking that 30,000 DPI in the sensor is overkill, and that no human can move a cursor with that accuracy, you’d be partially correct. The 30K sensor is meant to provide increased resolution and accuracy for its ability to detect movement, and not for you to spin around 10 times during a single jump.

In practical use with a fast-paced game like Overwatch, setting the mouse sensor to 30K and the in-game sensitivity to 1% results in the same physical mouse moves required to control the reticle, but the way the reticle moves is so much smoother. This allows me to track targets with more precision and consistency, and the difference is pretty apparent when watching an opponent’s kill cam as their reticle jitters around the screen, like it’s skipping frames.


Additional enhancements on the Viper V2 Pro include AI-powered Smart Tracking, asymmetrical cut-off, 3rd-generation Razer Optical Mouse Switches, and a more textured body surface that provides a bit of extra grip. Also supplied with the mouse is a set of Razer grip tape, pre-cut to offer customized cushioning and a non-slip surface. I went for the “shooting glove” layout, applying grip tape everywhere except for the trigger finger so I can rapidly fan the left button, if necessary.

Should You Buy the Razer Viper V2 Pro?


The new Viper V2 Pro is the Formula 1 race car equivalent for gaming mice. It’s designed to be the lightest and fastest possible version of itself, with the sole purpose of giving you a performance advantage when gaming.

While no compromises were made in terms of said performance, certain lifestyle elements were removed as part of its quest for minimal weight. Razer’s signature Chroma lighting is sadly missing, there’s no tilt scroll on the wheel, it’s not compatible with a charging dock, and the two right-side buttons were removed.

But all of the other benefits of having a Razer device remain, like performance customization via Synapse 3, on-board profiles, lag-free Hyperspeed wireless connection, and fast USB-C charging.

The Razer Viper V2 Pro is available now in black or white for $149.99, and can be found at Amazon, Best Buy, and the Razer Store.
