Razer Viper V2 Pro review: The best Razer mouse so far

An average size M chicken egg weighs 55 grams. A modern gaming mouse usually weighs between 55 and 70 grams. And then there is the new Razer Viper V2 Pro, which is an extension of the manufacturer’s Esports mouse series and even undercuts the previously lightest model, the Viper Mini. But what the manufacturer has saved on the wireless mouse’s weight, it packs on speed in the sensor and wireless connectivity. The result is impressive, as our Razer Viper V2 Pro review shows.

Razer Viper V2 Pro review: what’s included

Black box, toxic green sides and white and silver lettering respectively. The packaging of the new Razer Viper V2 Pro reflects the manufacturer’s familiar design language. In return, the scope of delivery inside offers several surprises.

On the one hand, there is of course the gaming mouse itself, and of course the obligatory manual including two manufacturer stickers. In addition, there is a fabric-covered Razer Speedflex cable, which is used for the wired connection or charging of the mouse via USB-A to USB-C.

Furthermore, the V2 Pro comes with a set of mouse grip tape, which can be used to improve the grip for particularly heated battles if desired. A 2.4 GHz wireless receiver with USB-A port and a USB-A to USB-C dongle adapter round out the scope of delivery.

Design and Workmanship

When it comes to design, the Razer Viper V2 Pro takes its cues from the looks of its siblings like the Viper 8K (our review). For us, this is a good decision, as the symmetrical design not only allows it to be used by right- and left-handed users, but also allows it to be used with all common grip types.

For our test, the manufacturer provided us with the white model of the gaming mouse (Mercury, or White Edition). However, the Razer Viper V2 Pro is also offered in the classic black color scheme and we can probably expect a pink-red Quartz variant at some point in the future.

But back to the design, which is largely based on the Ultimate model. In direct comparison, however, it is noticeable that the two right side keys have been reduced – among other things, to save weight.

However, the same offset main buttons and the two rectangular rounded side buttons on the left side of the body have remained. The clickable scroll wheel on the V2 Pro is now black with a white border. This looks noble. Below the wheel, we find an LED display that informs about the battery status (four colors) and the selected DPI mode. However, the newest member of the Viper family does without Razer Chroma RGB lighting.

A look at the underside reveals further innovations. On the one hand, the design of the PTFE gliding feet has been changed. We now find two smaller strips on the top and one continuous strip on the bottom. Rounded off by a PTFE frame around the new sensor, but more on that later. Another new feature: the DPI and power buttons have now been combined, which Razer says should improve functionality while reducing weight.

Workmanship of the Razer Viper V2 Pro

In typical manufacturer fashion, there is nothing to complain about in terms of the Razer Viper V2 Pro’s build quality. Of course, this is especially noteworthy due to the low weight, which also comes without honeycomb patterns or other air holes. In combination with the slightly roughened surface, the gaming mouse delivers a very pleasant feel and sits well in the hand.

Sensor and practical test

When I first examined the Razer Viper V2 Pro, I was surprised at how light the gaming mouse really is in the end. 59 grams for the white model (58g for the black Viper) stands out, making it one of the lightest mice on the market.

Compared to the equally heavy SteelSeries Aerox 3 (2022 Edition), the V2 Pro feels more comfortable in the hand. On the one hand, this could be due to personal feeling and the greater length with a simultaneously narrower body. On the other hand, however, also continuous body without holes or honeycombs.

Even as a left-hander, the V2 Pro is very comfortable to use. The two left side buttons have been raised a bit compared to the other Vipers, which makes them easier to feel in the heat of the moment.

Thanks to its symmetrical body, the Razer Viper V2 Pro is also convincing for left-handed users

In addition, the redesigned main buttons are immediately noticeable, which now trigger even more tactilely and with a very pleasant (quite deep) clicking noise. Specifically, these are third-generation optical mouse switches that are supposed to withstand a whopping 90 million clicks.

With five programmable buttons (or six in combination with the DPI button), the Razer Viper V2 Pro offers fewer DeepL accesses for actions than, for example, the Ultimate does eight buttons, but that’s more than enough for most gamers.

Fast, faster, Pro: The 30,000 DPI sensor

The Razer Viper V2 Pro is pretty darn fast. Among other things, the gaming mouse has the new sensor to thank for that, which the manufacturer has once again designed in-house together with PixArt. Focus Pro 30K is the name, and it allows up to 30,000 DPI.

That is so fast that the mouse pointer flies across the screen once with minimal movements. And still another 4,000 DPI more than the Corsair M65 RGB Ultra (our review), for example, allows. Whether anyone really needs such speeds remains to be seen.

At the same time, the nager is supposed to offer up to 99.8% precision on many additional surfaces due to the more precise sensor. This includes glass surfaces that are at least 2 mm thick. We couldn’t really test this in practice, but the V2 Pro works just as precisely on a cardboard box, a felt pad or the glossy desk as it does on the mouse pad.

Additional precision is provided by the excellent PTFE feet, which have very good gliding properties and help the gaming mouse to a maximum mouse acceleration of 70G (in comparison: Razer Ultimate offered 50G) and a speed of 750 IPS (compared to 650 IPS).

Thanks to AI features, the Razer Viper V2 Pro instantly adapts to different surfaces in Smart Tracking or allows for an “asymmetric cut-off”, thanks to which landing distance and lift-off distance can now be adjusted in 26 steps.

Battery: runtime and latency

The Razer Viper V2 Pro’s battery has also undergone a major overhaul. Apart from the fact that the gaming mouse is now conveniently charged via USB Type-C, which is an advantage compared to the microUSB port of the Ultimate, the battery now lasts significantly longer with a runtime of around 80 hours.

By the way, this value is based on constant mouse movements at the maximum possible polling rate of 1,000 Hz. However, since no one is likely to move the mouse for 80 hours at a stretch in practice, the runtime turns out to be all the longer.

Razer Viper V2 Pro
The V2 Pro operates wirelessly in the 2.4 GHz band. Nearly 80 hours of battery life are on the books.

After 5 minutes without input, the gaming mouse also turns itself off. While charging, the V2 Pro can of course still be used or simply be used wired. Thanks to Razer Hyperspeed Wireless technology in the 2.4 GHz wireless network, the input delay (latency) is around 0.2 milliseconds and is thus virtually non-existent.

Software connectivity: Razer Synapse

As always with a Razer product, the proprietary Synapse software is used, which automatically downloads the required drivers after the first connection with the Viper V2 Pro. All keys can then be assigned with new functions or macros in the tidy interface, as well as a second set of assignments thanks to Hypershift.

In the “Performance” section, you adjust the five adjustable DPI levels, optionally in the X and Y axes separately, as well as the sampling rate. You can also set Smart Tracking and specify when the mouse should go to sleep when inactive (between 1 minute and 15 minutes) and when it should enter power-saving mode (between 1 percent and 100 percent).

Razer Viper V2 Pro review: conclusion

After the 8K and Ultimate models, it would have been hard to believe that the Viper model series had any room for improvement in any areas. And yet, the manufacturer has managed to optimize an excellent gaming mouse with the Razer Viper V2 Pro.

On the one hand, this is due to the once again reduced weight without the haptics or ergonomics suffering. On the other hand, the gliding feet and speed have improved, while the sensor with a performance of 30,000 DPI should meet even the most extreme demands.

The fact that we have once again relied on a polling rate of 1000 Hz can be forgiven in my eyes. I hardly noticed a difference to 8,000 Hz anyway. In combination with the fast wireless connection and enormous battery life, the Razer Viper V2 Pro actually offers no reason for criticism. At least, if the five programmable buttons are enough for you.

Of course, we are clearly in the premium segment in terms of price, but the performance offered is certainly worthy of it. Especially since the Viper Ultimate is even more expensive and is only ahead in terms of the number of programmable keys and the RGB lighting.
