Customer Ratings & Reviews

Mouse works super well! Right out of the box it is really well made and easy to use. The battery also lasts a long time! The wireless receiver is also really small so it doesn’t get in the way.

I purchased this product during sale from Best Buy . It was timely delivered. It’s been 2 years since I purchased the product and there hasn’t been single issue with the mouse. It works flawlessly with high precision and high DPI. It is highly customizable and you can user razor software to play with RGB. I would happily recommend it to any one for gaming.

Best mouse I have ever owned. Wireless is a must for a gaming mouse. No lag, charges great with the dock I bought for it.

Best wireless mouse by far. Though it’s all preference in size and shape, I definitely like this low profile mouse compared to the Logitech g pro wireless. Very lightweight, easy to use with razer synapse. I recommend getting the charging dock with it as well

I've been using Razer since the beginning days of the boomslang mouse to the original blackwidow keyboard. The mouse is very responsive. it's lightweight and perfect for the claw or fingertip style grip. This was a great upgrade for me.

Been using for 2 years and could say it’s a beast of a mouse. My favorite out of the g305 and the Logitech GPW.

The Razer Viper Ultimate is a gaming masterpiece. With its HyperSpeed wireless technology, this mouse offers unrivaled performance, boasting high-speed transmission, minimal latency, and seamless frequency switching. Its Razer Focus+ 20K optical sensor provides precision like no other, ensuring your every move is tracked accurately. The extended battery life of up to 70 hours and the robust Razer optical mouse switch guarantee long-lasting durability. Customization is a breeze with eight programmable buttons, while the lightweight design enhances control. It’s a versatile gem, compatible with both Windows and Mac computers. The Razer Viper Ultimate elevates your gaming experience to new heights.

Solid ambidextrous mouse! Great shape, good sensor placement, and excellent LOD. But not for small hands unless you palm grip… I’ve gone through quiet a few mice from g400, g402, g303, gpro, g403 wireless, g900, g305, GPW, g303 wireless, EC2-A, FK2, ZA13, S2, model o, model o-, model d-, mm711, and Orochi V2. And in terms of LOD, weight, and overall quality I would have to have rank at #1 tied with g303 wireless. Unfortunately I had to return it just cause it was pretty big. I love the shape but I’ll have to wait for a mini version. Ended up getting the Orochi V2 and am really happy with the shape/size even if the LOD is not as great.

This is a very nice mouse, though not the flashiest, so if you really love the Razer RGB, might want to look at a wired Basilisk or something. The Viper Ultimate is surprisingly light - it almost feels like a toy, and because it's so light it can give off a first impression of being cheap. But this is a fantastic mouse - it took me a few days to get used to the shape, but once I did I really appreciated the feel and especially the weight - not having to drag a heavy mouse around a pad does make a difference in general use, not to mention games. Plus, the optical switches give me confidence this mouse won't develop the dreaded double-click issue...like my Logitech G502 did. This was a very welcome upgrade.

I have two of these that share one dock that I use for regular computer use as well as for gaming (mostly FPS games). I have large hands and worried that this would not big enough, but this mouse is very comfortable in hand. I love how light it is and the clicks feel satisfying. My only minor gripe is that the side thumb button don’t stick out as much as I would like. Battery life is excellent and much better than my Basilisk Ultimate (which I somewhat regret getting).

Great build quality, very lightweight and great for FPS games

Light mouse and like how clicky the buttons are. Battery will last a few days with the rgb on and charging is quick.

This mouse is good but it could be much better. The razer software is needed to control the mouses rgb which is unfortunate because the software is horrible. However the mouse itself is great besides the mushy buttons, the battery life is fantastic, it’s light weight, and very comfortable for most hands.

This mouse is very similar to the g pro, I only have the superlight, The right sided buttons are hard to click as a right handed user since they are so inset. I dont really use them. as it causes me to change my grip. No buttons other than the scroll wheel at the top and no tilt on scroll wheel. It is flatter than the superlight though. I am using this as palm grip [warm up mode] and will switch to g303 when i go claw [serious mode]. I believe viper v2 should be coming out very soon which is why these are discounted and included in bundles. This does not effect my decision. Only thing this is actually better than logitech is that you can macro the left click and right click and scroll wheel up and down [u cant in logitech devices]. Only reason to get razer peripherals, is that all buttons are remappable. [vs logitech]. I do like razer mics [but logitech owns blue mics now]. and the Tartarus pro. [no equivalent logitech game pad]. Would probably recommend a logitech as a main mouse and MAYBE a razer as a second piece.

excellent wireless mouse. precise tracking, with a good amount of dpi. light weight and fits in the palm very easy. has 2 side buttons and a scroll wheel. battery life is also good. rgb logo is a plus.

Excellent mouse, no delay, fast response, and I’ve had mine for more than a year now and it’s still by far one of the best mouse’s I’ve purchased.

Great mouse! Love the weight and feel of it. Made my gaming feel way more fun. Only drawback is sometimes the L / R buttons feel like they don't rebound from a click so instinctively may not feel like you can click again.

This is a great top of the line wireless mouse from Razer especially if you’re into competitive FPS games. It’s light (73g) without holes and the rest of the buttons and overall build quality is great. I did have a unit which had a loose cover for the dongle, but I got it exchanged and all was good. This mouse at the end though for me just didn’t work out when it comes to the shape. I found the hump to be too low as a relaxed claw gripper and ended up getting a G Pro Wireless instead a few months later as it had a higher hump and matched this mouse when it comes to the rest of the specs. Both this mouse and the G Pro Wireless are usually on display at Best Buy so I’d suggest trying both out before buying either to see what you prefer.

I really used this mouse for a long time, until I learned about vertical mice. I am keeping it as a backup though. I appreciated the variable sensitivity (accessed through the button on the bottom), and found it to be a very reliable device. I also like how the paint doesn't show any wear yet, unlike most competitor mice do after a few years of use in a warm room. I was pretty happy with this Razer product. I can't say that surprises me at all.

The Viper ultimate is a powerful mouse I used for awhile and accomplish the goal very well. It is built well even though it is plastic. Would recommend
