Customer Ratings & Reviews

This is peak performance for a mouse,an 8000kz polling rate,about 63 gram weight mouse or lighter,and ambidextrous mouse???? Thats the razer viper v4,all of this packed into one light mouse,amazing for gaming and rhythm games and especially for fps shooters,overall,best mouse and most user friendly mouse Ive ever used!

Very light very responsive good grip tape included

very smooth It feels incredibly responsive and tracks perfectly. I used to think I could only get used to heavy mice—that is, until I found the V4 Pro. It completely changed my perspective on lightweight mice. It's absolutely fantastic!

Literally the best mouse I’ve ever had. If you have a big hand or work out a lot and tend to “have a bigger hand like I said, then this is your mouse” it’s great and very very responsive! I’ve tried many expensive gaming mouse, but this one is GREAT. 10/10

The mouse is great. Very light. Works seamlessly with no lag when using it wirelessly. Cord is long enough to reach further away spots that you need to reach.

Mouse works amazingly. The 8000 polling rate is great and still lasts pretty long on battery using it.

I'm no stranger to gaming mice. I'm not even a stranger of expensive gaming mice. Considering the build quality and performance to a similar yet cheaper mouse I owned before, the perks of performance are quite evident. Charging is pretty fast with fast response times, definitely a must for more serious gamers.

Almost swapped mice from how tinny and loud clicks are, but it is perfect in every other way. Battery life is incredible compared to Viper V3 Pro

I have used many Razer products over the years, and this has to be the most responsive mouse to-date. I purchased this to mainly play FPS games, and it has honestly improved my gameplay on its own. I do have to be careful not to press too hard on the left click because it's just that sensitive which is great. I also love how much customization there is with the polling rates and dpi.

I believe this is the peak of mouses if you're willing to spend the money. Everything from the coating, scroll wheel, clicks, side buttons, battery life, and etc are top tier for a mouse. As well as having an web app instead of forcing to download synapse is great for less bloatware. Some concerns could be how loud the clicks but wearing headphones negate the sound so this is a problem for whoever you live with and as well as when I started using this mouse it felt pretty floaty at first but within hours it felt natural to use.

I’d give it 4.5 stars. Coming from the Logitech Superlight 1, I decided to try the Viper V4 Pro. The first couple of days felt a bit off, but once I got used to it, I ended up loving it. Smooth tracking, great clicks, and perfect for CS2. Highly recommend.

I had the V3 before this and I loved that mouse. This one just as great and battery life seems so much better. Worth the upgrade for me.

The Razer Viper V4 Pro is one of the most impressive wireless gaming mice I've ever used. Right out of the box, the ultra-lightweight design makes it feel incredibly fast and effortless to move, which is perfect for competitive FPS games. The shape is comfortable for long gaming sessions, and the textured finish provides a secure grip without feeling bulky.

Love this mouse. Build quality is solid and it a significant upgrade over the V2 version.

It’s honestly a solid improvement over the v3 pro, I don’t know what it is about it but it feels way more dialed in and in turn it’s helped me be more consistent in fragpunk

My Viper V2 finally broke and it was time for an upgrade. The V4 has a similar shape to the V3 which I like. The clicks are also noticably louder, which can be an issue for some.

Bought for cs2. Good mouse nice light weight. Nice clicks. Would recommend

This mouse works great and is perfect for gaming, its lightweight and duarable

A little pricey but really great overall. Lightweight and smooth. I was waiting for this and am really loving it!

[Employee of bestbuy] I swap my peripherals very often and in the last year, I’ve used four different mice and I would say that this is probably my favorite one coming from the razer Viper V3 Pro. Shape is great battery life is great. The new dongle is great compared to the old one and you no longer need to have sypnapse installed because they introduced web based software which is great. Overall this is just a great mouse.
