Razer Viper V2 Pro Mouse Review

Yet again Razer raise the bar for the lightweight gaming mouse market.  The Razer Viper V2 Pro is a top-tier gaming mouse you should be considering.


Razer Viper V2 Pro Review: Verdict

A top tier gaming mouse that will not disappoint.  Razer have done it again.

Razer is raising the bar for the best lightweight esports mouse, attempting to battle Logitech for the top spot.  But how does this successor to the highly successful Razer Viper Ultimate stand up?

In this Razer Viper V2 Pro review I will walk you through all the features it has to offer and what differences this upgraded offering has compared to its predecessor.  If you already have a Razer Viper Ultimate stick around to see if it is worth upgrading.

Design & Build

Size & Dimensions

Razer has kept most of the design aspects of the Razer Viper Ultimate. Due to that mouse’s huge success, it is a safe bet. There are some small changes though that go a long way to improving the overall package.

Razer decided to do away with the charging dock which is an improvement, removing unnecessary desk clutter. The Viper V2 Pro weighs 58g in total which is 16g lighter than the Razer Viper Ultimate at 74g. The weight difference is definitely noticeable and the mouse does feel very light in hand.

Part of that reduced weight is likely helped by the removal of the right-hand side buttons.

The sides of the Viper V2 Pro are plastic which is an improvement on the Razer Viper Ultimate’s rubber grips. These were very prone to crumbling and wearing away after a lot of use.

To compare both mice check out our Razer Viper Ultimate review.

The shell is made of a textured plastic which is different from the likes of the Logitech G Pro Superlight which has more of a matte finish. The textured plastic is slightly easier to grip and doesn’t suffer from the smooth texture that happens on the G Pro Superlight after extended use. There is no noticeable flex in the shell it feels solid and durable.

Unlike its predecessor, the Viper V2 Pro does not have any RGB lighting. The only light on the mouse is a small LED near the scroll wheel to help distinguish the current CPI setting. The mouse is available in both black and white colour options.

Shape & Grip Style

For reference my hands are 17.5cm x 9cm

The shape of the Viper line has always been a low-profile hump with ambidextrous side grips.  Razer has kept the same idea here with the Viper V2 Pro.  The hump on the mouse is very low so it is designed more for fingertip grip and claw grip players.

Palm grip players can still use this mouse and be successful however the low hump means it does not provide the same support and if you have larger hands you may find your fingers extend past the end of the buttons.

Sensor & Performance

Razer Viper V2 Pro Sensor

The Viper V2 Pro uses the latest Razer Focus Pro 30k which has a minimum lift-off distance of 1.2mm and a maximum polling rate of 1000hz.  There are a few polling rate settings on the mouse itself which are 125Hz, 500Hz, and 1000Hz. Using the 4k dongle the V2 Pro can reach up to 4000Hz polling rate. Generally, though it is recommended to always use the highest Hz setting.  The CPI can be configured from 100 up to 30,000 (hence the name) with increments of 50.

One of the additional benefits of Razer’s Focus Pro 30k is the new setting Asymmetric Cut-Off’. This allows you to customise the lift-off and landing distance independently.

The Viper V2 Pro also tracks on glass so if you are using a glass desk you won’t have any problems. However, it is recommended to get a mouse mat for gaming!  It is rare to find any issues with the latest sensors in gaming mice and Razors Focus Pro 30k is no different.


Razer Viper V2 Pro Side Buttons

Razer’s own Optical Mouse Switches (Gen-3) are behind the buttons which are rated at 90 million clicks. They state there are no double-clicking issues (shots fired at Logitech’s history).

The clicks feel very high quality, definitely at the top in terms of tactile feel and feedback. They are slightly louder than their rival Logitech’s G Pro Superlight but nothing too overbearing.

The side buttons have also had a small change, they extend from the shell more for easier access which is a great improvement over the hard-to-click predecessors. The side buttons also feel tactile and have a short travel time.

There are 6 buttons that can be configured via the Razer Synapse V3 Software. These can be set to launch shortcuts, keyboard functions, switch between profiles, and control multimedia. You can optionally set a hypershift button which allows a second layer of programmable button assignments.

The profile switcher/power button on the bottom of the mouse is not programmable.

Scroll Wheel

The scroll wheel is a notched, 24-step scroll wheel. There is no scroll wheel tilt but overall it feels crisp and the textured feel makes it feel very grippy. It is also quiet when scrolling quickly.

Mouse Feet

The stock feet on the Viper V2 Pro are perfectly fine. They won’t beat out any third-party alternatives but they are still smooth virgin PTFE pads. There is no noticeable difference with the feet compared to its nearest competitors.

Connectivity & Charging Or Cable

The Razer Viper V2 Pro supports wireless via its USB receiver. This differs from the dock that came with the Viper Ultimate.

Wireless gaming mice have come a long way and most mice on the market no longer struggle with disconnects or tracking problems due to wireless connectivity. From testing the Razer Viper V2 Pro is no different.

As stated previously there is an optional upgrade to the 4000Hz polling rate dongle but I don’t believe it is worth the extra cost.

As for battery life, Razer has upgraded this as well over the previous version boasting a play time of 80 hours which is 10 more than before. It has a reasonable charge time of around 2.5 hours.

The mouse can also be used while plugged in via its USB C cable. The cable is very high quality but not the lightest. It does not snag or have any glide issues but the mouse is best used wireless. Due to the fast charge times however using the cable will be a rare occurrence.

Durability & Warranty

From our current testing, there have been no noticeable concerns regarding the durability. Razer has suffered in the past with some button clicking inconsistencies and side grip durability issues however these seem to be much improved here.
If there are any issues the mouse is backed by a 2-year warranty and Razer’s RMA procedure is very straightforward.


Razer Synapse V3 can be used to customise the Viper V2 Pro’s settings. This includes adjusting the polling rate, CPI, button mappings, and the new features such as the Asymmetric cut-off.

Razer Synapse V3 is a significant improvement over V2 and is easy to use.

Razer Viper V2 Pro Review: Verdict

A top tier gaming mouse that will not disappoint.  Razer have done it again.

That’s a wrap on our Razer Viper V2 Pro review.  Overall the mouse is a top-tier contender for the best gaming mouse available right now.  It has all the features you need in a lightweight gaming mouse, particularly because it’s wireless too.  Razer is raising the bar yet again. 



Does the Razer Viper V2 Pro come with the 4k polling rate dongle?
No, the Razer HyperPolling Wireless Dongle is shipped separately. We believe it is not worth upgrading to this.

What is the Razer Viper V2 Pro’s battery life?
Razer state 90 hours however it was closer to 80 hours with our testing.

How long does the Razer Viper V2 Pro take to charge?
Around 2.5 hours.

Should I upgrade my Razer Viper Ultimate to the Razer Viper V2 Pro?
If you want a lighter mouse yes. Overall the V2 Pro is a solid upgrade over the Razer Viper Ultimate.
