I've been playing video games on PC with a mouse and keyboard since just barely reaching a double-digit age, so naturally, I tend to generally be pretty good at them. Even so, though, I'm not much of a competitive player, and my aiming talent falls a few rungs below where the hardcore sweats sit on ranked mode ladders.
I've never really felt the drive to try and climb those ladders, either, and so I've never gravitated much towards expensive, high-performance gaming mice that come with the latest and greatest specs. That being said, when I got the opportunity to review Razer's new Viper V4 Pro, I was very curious and excited to see how I'd like it compared to my beloved old CORSAIR Harpoon.
After putting it through its paces for over a week, I'm happy to say that this mouse has made me feel like the competitive gamer that I'm not with its top-notch specs and performance, supported by a featherlight, yet durable chassis, excellent battery life, and a nifty wireless dongle with a few simple, yet useful features. It's a sizable improvement over its Razer Viper V3 Pro predecessor, and an elite choice for hardcore players. Just be ready to accept that it won't be yours for cheap.
Razer Viper V4 Pro: Specs and availability
The Razer Viper V4 Pro retails for $159.99 and is available now, both directly from Razer's website as well as through digital retailers like Amazon and Best Buy. You can get it with either a black or white colorway, with the only difference between the two aside from color being that for whatever reason, the white one weighs one gram more (you won't feel that).
Built with reinforced plastic, the mouse weighs just 49-50g, and is also packed with the most advanced specs Razer has ever put under the hood of its gaming mice. Here are its full specifications:

What's the Razer Viper V4 Pro like?
Given that the Razer Viper V3 Pro was determined to be the preferred mouse of the majority of over 2,000 polled pro players, I had high expectations for its successor going into this review. After using it for over a week, though, I'm pleased to report that it lives up to them and then some.
In Bungie's new competitive extraction shooter Marathon as well as both Battlefield 6 and Helldivers 2, aiming with the Viper V4 Pro has felt extremely precise, smooth, and snappy. The impressively accurate third-generation Focus Pro 50K Optical sensor is to thank for that, as is the top-notch 8,000 polling rate that ensures very responsive and latency free movement.
With a max DPI of 50,000 — a large increase over the Viper V3 Pro's 35,000 — the mouse also gives players a huge range to experiment with alongside in-game sensitivity options to find the setting that's perfect for them.
Coming in at 49g (50g if you get the white version), the mouse is also incredibly lightweight, which is always a plus for mice aimed at competitive gamers since they can be moved around faster. The reinforced plastic chassis ensures durability wasn't sacrificed to achieve this, as do the Optical Gen-4 switches rated for 100 million clicks.
The switches are a bit clicky and loud for my personal tastes, but given that I'm wearing a headset all the time, they didn't truly bother me. Notably, the mouse also sports an optical scroll wheel that's wonderfully smooth to use, along with two buttons on the left side you can remap through the Razer Synapse software (the app or the web-based version). Synapse also lets you tweak and calibrate a wide range of settings to get the mouse feeling just right.
At a max of 180 hours, battery life is also a significant step up from the Viper V3 Pro's 95-hour peak, though Razer says this drops to 45 if you're using 8,000Hz instead of 1,000 (you can switch between 500, 1,000, 2,000, 4,000, and 8,000). In my testing, I found this to be pretty accurate, so expect to charge the mouse around once a week if you play with max polling rate.
Lastly, there's the half-spherical puck that serves as the Viper V4 Pro's wireless dongle, and it's excellent. Not only is its connectivity flawless, it also has three color-changing LED indicators that display the quality of your connection, the mouse's current battery level, and the polling rate preset you've selected.
Razer Viper V4 Pro: Conclusion
Ultimately, the Razer Viper V4 Pro is arguably best-in-class for the type of mouse that it is, but that doesn't necessarily mean it's going to be the right mouse for everyone. $160 is a lot of money to spend on an accessory when you can get good mice for far less, even if this one is terrific and a dream to use in FPS games. I received it for free for this review, but honestly, I wouldn't buy it with my own money.
With that said, if you're a hardcore competitive gamer, you're looking to get your hands on the best, most impressive gaming mouse, and cost isn't a huge factor for you, then I strongly recommend the Razer Viper V4 Pro. I have a feeling that, as its predecessor did before it, this mouse will rapidly become the preferred choice of many pro players.
