Razer Viper V4 Pro

T Trusted Reviews Reece Bithrey · reviewer

They’re wonderfully clicky and a little on the louder side, but they were immensely responsive in conjunction with everything else the Viper V4 Pro offers.

One thing that was a welcome surprise was teh change of dongle. Included in the Viper V4 Pro is a dome-like dongle. Using the Razer Hyperspeed Wireless Gen-2 syste, it aims to be over 60% more efficient. Flashing latency by 55% of the previous generation of dongles. This might even prevent those annoying little drops in connection that wireless dongles quite often suffer from.

And according to them, the V4 Pro features their biggest technological updates in 10 years as it features new switches, a new sensor, an optical scroll wheel, and more. All packed into the loved death adder ergonomic shape that still managed to cut some weight as well. So, let's check it out closer before we get into the technical stuff. And yes, as you can see, the shape remains unchanged.

The Razer Viper V4 Pro doesn’t look all that different from the Viper V3 Pro . Razer kept the Viper V4 simple and effective just like its predecessor, except with more oomph. The Viper is still a somewhat niche product. It’s an excellent gaming mouse , but I wouldn’t go running to it unless you are a serious competitor.

So winner for this category is the V4 Pro for its pure speed and just being the lighter one. Now for the sensor and tracking Superlight 2 has got the Hero 2 and it is proven to be precise and consistent. And I've been using this mouse for around 1 and 1/2 years now and I'm pretty sure that this is true.

You basically feel nothing, but what you do feel is very centred during use, not a big heavy sensor in the middle, but more spread out across the hand, making it quite effortless to move and reducing fatigue, as I was testing it on my laptop for work and also gaming at home, so I have a fair few hours of straight use.

All of your weight junkies out there better go running and buy it right now. But now, there are some differences. But honestly, looking at them just like this, you're not going to be able to tell one from the other. I honestly couldn't tell you which one's which right here. How you're going to be able to tell the difference is number one being with the dongle.

The Razer Viper V4 Pro is, objectively, an outstanding competitive gaming mouse. Even in its slightly heavier white trim, it’s preposterously light without feeling flimsy, brutally fast without sacrificing control, and packed with the kind of sensor and wireless tech that makes latency graphs look flat.

B boardzy boardzy · 249K subscribers · Apr 2026

Um, with the Viper V4 Pro, since it is 10 g lighter at 50 g, and there's no issues with the weight balancing, like it doesn't trend front-heavy or back-heavy. Um, the Viper V4 Pro, it definitely feels like a quicker mouse in motion, and you can combine that with the fact that the sensor, like, the motion latency is technically lower.

H Hardcore Gamer Cory Wells · reviewer

Razer has shadow-dropped its latest and greatest Viper V4 Pro as it follows in the lineage of its predecessors while aiming to be the top technical gaming mouse on the market. This is available now, and it can be made even more detailed with the release of the latest Gigantus V2 Pro mouse mat.

B boardzy boardzy · 249K subscribers · Mar 2026

No doubt the weight reduction and new 3955 sensor/frame sync are nice features

The improvements are subtle individually, but together they create a mouse that feels exceptionally well-tuned for competitive play. Most of my testing was done in Marathon , it didn’t matter what I was doing in-game, the Viper V4 Pro responded exactly as I expected.

T The Provoked Prawn The Provoked Prawn · 185K subscribers · Jun 2026

The Razer mouse has classically clicky and loud switches and is very responsive and a lot of fun to game with. And the Logitech Pro X 2 Superlight is interesting cuz it uses the revolutionary haptic inductive trigger system with adjustable actuation and a very interesting setup.

T Tech Sportskeeda Mudassir Kamran · reviewer

The Razer Viper V4 Pro builds on a proven formula with meaningful upgrades where it matters. The brand refines one of its most trusted esports mice instead of redesigning it. Although the shape stays familiar, the focus shifts to meaningful internal upgrades.

J Jaeky Jaeky · 110K subscribers · Jun 2026

So, I'm very familiar with this mouse and the Viper shape, and I can confidently say that it's my end-game mouse. I've been using the V4 Pro for hours on end over the last few months, and I've noticed a genuine difference in my actual in-game performance, especially in Valorant. Since I'm playing at a high level every single day, consistency is everything to me.

P PC Gamer Article

The best wireless gaming mouse is the Razer Viper V4 Pro . It's managed to best even the stellar DeathAdder V4 Pro with a truly outrageous specs sheet and a feel that simply can't be beaten right now—although you will pay a pretty penny for the privilege.

E ECPU ECPU · 46.5K subscribers · Sept 2025

The best part is despite being so light, Razer still managed to make it very strong and rigid feeling. It doesn't feel like it has any flex at the sides and it doesn't make any creaking sounds. Very impressive for such a lightweight design. It's got an all matte finish and it seems to do a good job resisting sweat and fingerprints and it feels secure to hold during long gaming sessions.

Final thoughts: The Viper V4 Pro is one of the best mice I have ever tried. The only negative in my opinion is the scroll feeling. It reminds me of the regular GPX 2 side buttons: they work, they won't lose you any matches, but they don't feel great.

The Razer Viper V4 Pro is more than you think it is.

P PC Gamer Article

The Razer Viper V4 Pro is an all-round fantastic mouse, with stellar build quality, satisfying clicks, and a nicely tactile scroll wheel. It also balances top-tier performance and a light weight with a surprising amount of juice.

And I actually like it that way because it's been sitting nice and planted on my desk. I haven't had any issues with it sliding around on me or anything like that. There are three LED indicators up here on the front.

C COGconnected Article

First impressions matter, and right out of the box, this one delivers. Granted, it’s not flashy. There’s no RGB lighting or extra switches to fuss with. The design is fairly simple, but under the hood, it really excels.

T The Rage Academy The Rage Academy · 18.3K subscribers · Jul 2025

Overall, I consider the side button update a noticeable improvement. They feel more tactile and responsive with a nice clicky sound. Other than how the side buttons feel, the V4 also brings a new surface texture. And this one may divide some users. The texture on the V4 is silky smooth, which is totally different than the V3, which to me it feels like an eggshell.

P Pcmag Zackery Cuevas · reviewer

The full-featured yet low-profile Razer Viper V4 Pro is the best mouse for esports players who prefer a claw grip and enjoy fast-paced games like first-person shooters.

S stubby stubby · 5.9K subscribers · Mar 2026

This mouse kind of like opened my eyes to how good mice have gotten within the last 2 years. And starting with the build quality, it's no flex whatsoever. I could put as much force as I wanted onto that mouse, it wouldn't squeeze. to go find my force gauge meter, but I couldn't find it. But, with just general hand grip strength, I'm rating it at around 27 to 30 lb of force.

From the smooth and comfortable grip to the snappy clicks and responsive scroll wheel, it's safe to say that gaming performance here is virtually flawless.

I have literally just woke up on the best news ever. The Razer Viper V4 Pro is here.

The Razer Viper V4 Pro is already an excellent mouse, but paired with the right Gigantus V2 Pro surface, it feels more complete. More intentional.

J jerrorr jerrorr · 5K subscribers · Apr 2026

I've been using this mouse for around 2 weeks now, maybe even more, and I've been absolutely loving my time with it. On the outside, it might not look like it's a big upgrade over the V3 Pro, but honestly, when you start using this, the difference, at least for me, is very noticeable. Also, I want to mention that I did purchase this with my own money, and these are all my own thoughts about it. Bu

Razer's Viper V4 Pro drops to 49g, hits 180-hour battery life, and earns top mouse honors, but its switches are loud enough to wake the neighbors.

J jerrorr jerrorr · 5K subscribers · Apr 2026

So it's a very very nice mouse to have in your hand. The coating is also yet again fantastic and pretty much the best in business. It's their rubberized matte coating they now use. If you remember the first Deathadder V3s, uh they did not have this type of coating and it was instead the chalky rough texture that for me did not work at all. So it's very nice to see how far we've gone from that.

The Razer Viper V4 Pro is one of the best gaming mice I’ve used so far. There is little to nothing I can objectively fault it for.

The V4 Pro is packed with Razer's Focus Pro Gen 3 optical sensor, boasting 50,000 DPI, 930 IPS tracking speed, and 90 Gs of acceleration, making it one of the fastest and most accurate mice on the market. It's also equipped with Razer's Gen 4 optical switches, which are rated for 100 million clicks, so durability is definitely not an issue.

The Razer Viper V4 Pro, so good you’ll want to steal one for yourself.

But once you start digging deeper, you realize this is one of those upgrades where everything that actually matters has completely changed. And I mean, everything. Today we're talking about the Razer Viper V4 Pro. And this isn't just another refresh.

In terms of the coating, this has a really solid coating.

I won't pretend that the arrival of the new Viper V4 Pro didn't excite me because the Viper V3 Pro was one of my favorite mice. And since the body hasn't changed, but the internals got a solid upgrade, there was definitely something to look forward to.

Um, I went to the Superlight 2 and then I went to this one, but I think for 49 g, I think this is very solid honestly.

What makes the Razer Viper V4 Pro stand out is the combination of an incredibly lightweight 49 g design, next generation wireless performance, a 50K DPI sensor, true 8K polling support, and a shape that has become one of the most trusted options in competitive esports. This is a mouse built with one goal in mind, maximizing performance for serious gamers.

Wireless performance is excellent thanks to Razer's high-speed, low latency wireless technology. In actual gameplay, it feels virtually identical to a wired gaming mouse, which is critical for serious competitive players.

I IGN Samuel Horti · reviewer

If you want something simple, elegant, and ready to compete, the Viper V4 Pro delivers, with premium-level performance in a comfortable symmetrical shell. But if you want more bells and whistles (on the outside), and something to fit your unique ergonomic needs, then you should look elsewhere.

T The Provoked Prawn The Provoked Prawn · 185K subscribers · Jun 2026

If you want a gaming mouse with satisfying actuation, crispy clicks, high-end specs, and more, then the Razer Viper V4 Pro might be the one to consider. This is a beast of an upgrade to the Viper lineup, and one that you can make look really aggressive with the included grip tape, and yet it weighs in at just 50 g or thereabouts.

T Tom's Hardware Article

The Razer DeathAdder V3 Pro was practically perfect when it came to size, shape, and feel — and Razer knew better than to fix what wasn't broken with the Razer DeathAdder V4 Pro, which is why the V4 Pro is aesthetically identical to its predecessor.

T The Provoked Prawn The Provoked Prawn · 185K subscribers · Aug 2026

I really like both of them, but for different reasons.

Ultimately it's not for me because of the shape but if you have the budget and you've always wanted to try the Viper Pro shape from the manufacturer that originally created it, the Viper V4 Pro might be the way to go.

D DiamondLobby Reviews DiamondLobby Reviews · 72.4K subscribers · Apr 2026

However, it could end up feeling less stable as the mouse isn't anchored to your hands as much. Between them, their shapes are designed for specific reasons so there's no winner here. In terms of weights, the X2 Superlight is approximately 61 grams and the Viper V4 Pro is around 50 grams.

I Invision Game Community Craig Roberts · reviewer

The lack of RGB will absolutely annoy some gamers, and the premium pricing means this is not exactly an impulse buy. But if your focus is pure gaming performance, this mouse delivers in almost every area.

And the weight balancing is pretty bad. Um it's very front-heavy, and the weight is kind of high as well, but I mean, I'm used to it. I still think it's worth using um even though it's higher weight compared to a lot of other mice, especially the Viper V4 Pro. Um this does feel really nice though to hold and use because it is 49 g.

E Engadget Jeff Dunn · reviewer

The V4 Pro's updated internals may make it more durable over time, but if your hands are on the smaller side and you want an ergonomic shape, we wouldn't object if you grabbed the cheaper model instead.

But, in terms of the Viper V3, it's already so good that if you are tight on money, like the differences that you're going to get in terms of your in-game performance are probably exceptionally minimal. If If that's your main mouse and you care about having the best of the best on paper, then you're probably going to be somebody that might want to upgrade to the Viper V V4 V4 Pro.

However, as I talked about in the review, due to the unique shell materials they've used inside here, servicing this mouse is a little tricky. As well, they have made some improvements to this aspect of the mouse, which makes this mouse a little trickier to service than their previous releases.
