Customer Ratings & Reviews

Excellent product . One of the best mouse purchases I’ve made. I can’t personally notice any lag from it being wireless, and the battery life and docking station make it a pleasure to use . I would definitely recommend this for anyone wanting to cut the cord. Great for claw grip. Side grips are part of the mouse instead of being put on with adhesive , and the skates glide with zero pull or friction. Really premium product

Super lightweight and responsive and amazing battery life. i would recommend this to more people

the mouse is light, nice software program, really responsive switches as well as useful charging dock

This is a very high quality mouse for claw and fingertip position users. I love everything about it and the construction of it is 5/5. Extremely light compared to the other mice I’ve used (deathadder, logi MX series). Unfortunately I had swapped it out for the basilisk because prefer an ergo mouse for long term use for not only personal but work as well. Would highly recommend it at the correct price of 60 dollars today.

Buy it. Buy it. Buy it. It is VERY light and has great battery life. If you play any shooters BUY IT. Every review on the planet raves about this mouse for a reason. I tried the Razer Basilisk Ultimate and the Viper Ultimate. THE VIPER IS BETTER. Trust me. The Basilisk has a major flaw where the scroll wheel sometimes will not detect your scroll. This causes major problems when gaming. I return the Basilisk and kept this.

Im very impressed with the quality. Its very very very light. Super weird going from the brick gaming mouse i came from. It tracks very well and easily withstood my long hours of playtime battery wise. As far as cost is concerned I only paid 80 for it on sale so i got a lot more value than others possibly. The new software controlling razsr products is very easy to use and clean.

After 3 months I really liked, confortable and very responsive, a very good deal

Excellent mouse. I usually opt for a heavy weighted mouse, but was having some joint issues and a lighter mouse seems to have helped that. Mouse is great for gaming, almost no adjustment period for fps games. Usually play destiny pvp and won first match out of the gate with it. Wish side buttons were a little further back and larger but good comfy design. Charging dock is a great feature.

Very fast, light, and small. Perfect for professional level gaming

Was never a fan of wireless, but with my current one snagging with my desk clutter I searched for a good wireless mouse. I mainly do gaming and this one fits the bill. The dock is a nice touch and convenient, cheaper to get them as a bundle than buying them separately. I prefer a wider mouse (I have the deathadder), but this one is surprisingly comfortable (my pinky hurts after a while with G502)

Not my particular style of mouse but it looks great and is super light. Recommend greatly to most people. Cheaper option than the new V2 and I prefer the design of the ultimate. Dock is really nice and allows you to put the dongle in so you save a USB port. Very well built mouse with a good design.

I used the mouse right out of the box about a month before i had to charge it so it lasted a long time, even though I don't game a lot but still very impressive. Like it says, its very lightweight and cordless which is good when you're out and about. I like the charging dock, you can charge the mouse and use it as an extension for the dongle or plug the dongle straight into the computer.

I did not think I would love this mouse as much as I have. I came from a Mionix NAOS 7000 (used it since 2013). I wanted to try out new mice after the scroll wheel started to go out. I used the Viper Ultimate for around a week, then tried the Razer Mamba wireless, Deathadder V2 and the Corsair MM720. If the MM720 was wireless it would probably be my new mouse but wireless mice spoiled me. The Mamba hurt my ring finger after a while and the Deathadder just wasn’t comfortable. When I switched back to the Viper Ultimate, it felt like home. I also tried the Logitech G Pro Wireless (shroud edition to ensure the switches were newer) and the Glorious Model O wireless. The GPW was alright but not as good clicks or scroll wheel as the Viper Ultimate and the Model O was mushy for the side buttons and scroll wheel was too loose compared to all the other mice (I also could feel the holes on my palm and it did not feel good). Viper Ultimate is my Ultimate mouse thus far. I hope they make a Superlight version to compete with the new GPW X Superlight. My only con is the side buttons, I bought a grip tape set that has grip tape for the them and it solved one of the only issues I have with the mouse. My battery doesn’t seem to last as long as advertised but I am ok with it since the dock is so nice and convenient.

I've been a Logitech fan for awhile but their products have been slacking lately, so I decided to switch to another wireless mouse for my gaming needs and stumbled upon the Razer Viper. It's so light, I feel more natural playing games or just navigating. It feels great and I love the charging dock along with the wireless usb that plugs straight into it. Pretty neat and frees up a usb slot on the PC.

Can’t even tell a difference between this and my wired mouse. The mouse is RGB so you can rock any color you want. The mouse comes with a charging so batteries aren’t an issue. The battery lasts for a long time, but the logical thing to do is to always have it charging on the dock when your done. It also has a fast charging: about 15 minutes gets you a few hours. The mouse is also extremely light.

So good and i love the dock it has so nice and feels so good in my hand

Finally a pink mouse by Razer! I love how it's wireless, but if you forget to charge it, you can still use it while it's plugged in by a wire.

The quality of this mouse will not disappoint! The only other mouse that compares in this lightweight category is the logitech gpro wireless, and both mice have their ups and downs. However, what got me more invested into this mice is the fact that it comes with an RGB charging dock with could make any setup look good and display the mouse as decor when not in use. The performance pretty much compares (if not better) than the gpro wireless with one possible deal-breaker flaw: the buttons on both sides of the mouse cannot be removed. That means possible accidental clicking if not careful, and so I ended up having to disable the right side buttons (because I'm right-handed) via software and not let the accidental clicks bother me. The mouse itself is a bit on the low-profile, so it's much more suited for people who prefer finger-tip or claw grip vs the palm grip that most people go for the g pro wireless for. Overall, it's amazing how a wireless mouse like this can be so light and comfortable despite the insanely low weight of 74 grams. This could possibly be the endgame for any FPS shooters out there. It just a shame that the accidental clicks on the right or left side buttons could bother some people, and that can be a HUGE deal-breaker for some. Not me, though, I am VERY happy with this purchase.

Excellent mouse, it's very light weight which really helps with shooters. I play cs go and I find my aim to be much improved over my old mouse g502 (100+g). The wireless mode has negligible latency, it feels just as responsive as wired mode. The battery is also able to last through 10+ hours of hardcore cs go which is fantastic.

Best mouse ever. Super quick and responsive . It doesn’t weight anything it’s like an extension of your arm. The battery last for two days straight non stop . I also love the flexibility of the different options you have to charge your mouse. I forgot to me soon that the charging port and mouse with the lights makes it look amazing
