Customer Ratings & Reviews

This mouse is truly amazing. This mouse is very comfortable with its ambidextrous shape. This mouse is amazing for shooters due to its lightning fast latency and 74 gram weight. This mouse is great for claw grip and fingertip grip users. Palm grip is ok for people with smaller hands but not recommended for a mouse this size. This mouse also comes standard with 100% pure PTFE feet although you couldn't go wrong replacing them with corepads or hyperglides. If you're in the market for a high end lightweight wireless gaming mouse you should 100% consider the Viper Ultimate. If you want to try a lightweight wireless gaming mouse from other brands, I suggest you consider the Logitech G Pro Wireless/ G Pro X Superlight, Steelseries Aerox 3 Wireless, Glorious Model O Wireless,

I love this mouse. It's super light and glides with little resistance. The real star is the dock. It's easy to place on the charger thanks to the magnet, and the RGB interacts with video games.

I love it so far, I forget to charge it sometimes but it’s still never died on me, I love the color, haven’t had any problems, doesn’t lag like other wireless mouses I’ve tried, would but again

Bought this as a set for my gf and she loves it! I own the Basilisk mouse and I noticed this one is a lot lighter with almost the same functions and comes with a dock!! Great response time and very comfortable as well.

Great mouse. Very light busy solid build, solid responsive button clicks, ambidextrous, pretty good battery life. Razer software can be a little clunky but all good after you get your configurations set.

If you're looking to go wireless, this would be the go-to mouse. For the longest time, I was avoiding wireless mice due to battery life + latency. But after seeing reviews online speaking well about the mice, I decided to give into the hype, but man they weren't wrong about how good this mouse is. Didn't notice any latency issues since, it felt just like being wired, without dealing with the issue of cable drag of having a wired mouse since it's wireless. I disabled the RGB with on the mouse because it extends the battery life of the mouse up to about 70 hours. That's a LONG time. I'm able to game for my long hours without worrying about the mouse dying mid-session in-game. Would recommend this to anyone looking for a great lightweight wireless mouse.

Amazing mouse. Never had an issue with it. Lasts a long time!

*My first review ever, which says something, so take that into context as you continue reading.* I fell off the Razer Train for years as I explored other options in the PC peripheral space, but this one item brought me back. I'll keep this nice and short—this is the best mouse I've ever owned, BUT the Razer curse has also affected this amazing product. Their quality control is still not where it should be; the build quality of this mouse does not scream $150. It's not awful, but if you're meticulous or particular like me, you'll notice how loose the mouse buttons are, either right out of the box or within only a few months use. If that doesn't bother you, this is arguably the best wireless mouse (or mouse, period) on the market. If you don't mind wired, the base Viper is a much cheaper option to the Ultimate. If you need an esports-ready mouse that will last, try a Zowie or high-end Steelseries, or just try the much cheaper base Viper (there's also an even cheaper Viper Mini, but it's small). If you still want wireless, don't mind the price, but want better build quality, you may want to try out the G Pro Wireless. Hope this helps, still a great mouse but their QA (or lack thereof) may be a deal-breaker for some.

First razer product and wanted a wireless mouse. Dont know much about peripheral software so went ahead and bought this from a recommendation. Its been comfortable and easy to use. The RBG is a cool bonus (can be turned off).

This is my first lightweight and first wireless gaming mouse. I came from using the G403 for almost a year and even with a bungee to hold the cable back as soon as I swapped the the Viper the difference is night and day. It feels much lighter and you feel no pull which makes adjustments while playing very nice. The software is easy to use and well developed to adjust the rgb of the charging stand(which is very nice) and the mouse itself. I do wish that the the other side buttons could be mouse buttons 6/7 but instead they are programmed to 4/5 which you could reassign but separate assignments out of the box would be nice as well. Battery life has lasted for my average gaming sessions 4-5 hours per day so no complaints there. Overall a really well built mouse and no complaints so far.

Love it very lightweight and easy to use! Design is perfect

Owned the mice for over a year now and still it works great and is my favorite that I’ve owned so far.

I've had three different sets of the razer viper ultimate and every single one has worked perfectly for me. The new ones have a great click on both the side buttons as well as the main left and right clicks. The dock works well, but do remember to have the rgb turn off automatically at night as they are pretty bright. Others may not like the recessed side buttons, but they're a great mixture for no accidental inputs as well as being easy enough to press when needed. The only downside of the mouse for me would be the Razer Synapse software being a little buggy, but since I typically only use it once to set my dpi once, it's not too big of a hassle.

I had a older version mamba elite and bought this and oh my there was a huge difference in my aim. Not neccessarily my aim but latency had a huge roll also helps that the mouse was very light. Solid mouse great build/ quality would easily reccomend. I have the g pro wireless and g305 and this is by far my favorite mouse. For those with large hands just keep in mind that you may or may not have to change your grip from palm to grip. Buttons are solid and not mushy from my personal mouse and mouse feet are smooth and colored white which was a plus for me. Spend the extra cash and get the version with the dock as well. Looks super clean imo.

After using several different mice to determine which was the most comfortable, felt the most satisfying, and didn’t weigh too much, I bought the Viper Ultimate. I can easily say it’s the best wireless mouse I’ve used, and the best light form factor wireless mouse. Shape: the Viper Ultimate’s shape makes it a comfortable, easy to use mouse for almost all types of mouse grips. Claw, palm, and fingertip are all comfortable on the mouse, even for people with small hands like myself. The shape is comfortable and feels ergonomic while being ambidextrous. Weight: while it isn’t the lightest ultralight mouse out there, the weight feels great for a wireless mouse. It’s not too heavy, and it’s easy to use and maneuver around any mousepad I’ve tried it on. Currently, I use an Artisan Zero Mid XL pad, and have tried it with an Artisan Hien Soft, Dechanic Control and Speed, and other deskpads. With each, I have not found any issue with the weight and moving the mouse. Wireless Features: the wireless is fantastic. There isn’t any noticeable lag, and I’ve personally never had issues with the connection. Synapse hasn’t been difficult which is surprising, as previously I’ve had some problems with Synapse being finicky. The charging dock is great, and if the cable is needed to charge at some point, it’s not bulky or in the way. Battery Life: the battery life is the only thing that may be a bit lacking, but I haven’t had too many issues with it. I keep my lighting on 5-10% and it’s still easily visible, and the mouse lasts at least 3-4 days of 6+ hours a day, and generally more. I’ve previously use the G Pro Wireless, and I will say that the battery isn’t quite as long lasting, but it does the job and does it well. Other aspects: the clicks can be a bit “mushy” just in the sense that they don’t have a higher pitched clicking noise like the G Pro Wireless or like Glorious Model O’s, but I’ve never found mine to be bad or noticeable in that aspect. Tracking is great, and you can create custom tracking profiles within Synapse for different mousepads. The scroll wheel isn’t loud or intrusive, and the stock mouse feet are PTFE and great. I eventually replaced mine with Tiger Arc 2’s just to test them out, and the Razer stock ones are just as reliable unlike the GPW’s. Overall, the Viper Ultimate has easily become my favorite light mouse for use. We’ll see if that changes with the new GPW X Superlight, but shape wise the Viper will likely still beat that one out. The new Glorious Model O wireless mice are also coming out soon, so that’ll be something to test it against, but the grips on the Viper may end up winning out over the Model O’s smooth sides. If you’re looking for a good, reliable, comfortable lightweight mouse, go for the Viper Ultimate.

Pros: Battery life is great, very lightweight, good software, charging dock is great, ambi design, side buttons both sides. Cons: None, either then I would prefer more color options.

Used this every day for a year now, and although there are better more lightweight mice by now, this one still runs extremely well. The first time I picked it up I was surprised by how light it was. I went from a 150g mouse to this, and the difference was day and night. I had never accidentally pressed the side buttons on the right side, and the left side buttons are fine. I have it bound to walk in csgo, and it is a little hard to keep holding that while moving the mouse. One issue I had with the mouse is when the mouse feet worn out. I had used it for less than a year, solely on cloth pads, and the bottom of the mouse was already rubbing against the mouse pad.

I am a big Razer fan. I have their laptop, keyboard and mouse. The connectivity is easy. Love the RGB lighting. Battery life is great.

I've had this mouse for a while and haven't had any issues with it. I do wish that the side buttons were wired individually instead of being copies of each other.

The Razer Viper Ultimate is an amazing gaming mouse that's very versatile and handles anything you throw at it. Its performance is excellent and the latency is extremely low, whether you use it wired or wirelessly. It has an ambidextrous design with two side buttons on each side, giving you plenty of programmable options. It feels durable, well-built, and remarkably comfortable, with a low back and rather short body. Its smaller size lends itself well to a fingertip grip, but small and medium-sized hands will also find it comfortable with a palm or a claw grip. It also comes with a unique charging station that acts as a receiver range extender for better performance.
