Customer Ratings & Reviews

This mouse is amazing. Perfect for everyday use and FPS gaming. It's light, and very responsive. The Razer optical switches in each click feel good. Charging dock is something I didn't know I needed, and the wireless response time is amazing. Do not get scared by the price point. Worth every $$$

Lightweight, versatile, and responsive mouse. Although it is a gaming mouse, it works very well as a multipurpose mouse. The charging dock makes this a phenomenal value. The mouse frequently goes on sale, so if you can catch it then, even better!

Been using this mouse for awhile and I have to say it's an incredible mouse. I can't comment on its longevity yet(especially with the infamous double clicking problem that tend to happens in the future with many Logitech mice due its Omron switches as opposed to the optical switch in the Viper Ultimate), but in terms of ergonomic and smoothness of movement, the Viper Ultimate is great even if you're gaming and just using it for productivity. That said, I don't personally use the charging dock since I find it easier to use the mouse wired to recharge it. Probably the only flaw I have is that battery life could be better for the mouse when it's in wireless mode since it's only like 70 hours of heavy use. Meanwhile, the Razer Basilisk X Hyperspeed can have like 285 hours of battery life.

This mouse has served me for a year now between working as well as gaming, and it’s definitely a nice piece of kit to have. Initially purchased for the light weight claim, i started using the side buttons more for different tasks.

It's a great mouse I love it and synapse is not bad at all idky people be complaining about it but sadly the mouse is to big for my tiny hands so I have to give it away but if I had big hands I would had kept it

This mouse is perfect for FPS games! First of all, I got to admit this mouse has a pretty nice appearance compare to others. Secondly this mouse is light which is good for FPS games.

I had always used cheap mice up until I decided to go big with this one it was a great choice mouse works super well razer synapse makes customization easy and allows a lot of options feels good in my hand and is a super clean design highly recommend going with this mouse

I had a wireless GPro, G305, corsairs, but this mouse seems to be better than all of them. Besides the shape, weight, texture, it’s optical sensor seems to be the best I’ve seen. I will tell you 150$ is a lot for a gaming mouse but I couldn’t be happier with this thing on my desk.

So far it’s been an amazing mouse for full time gaming. Charged it lasts 2-3 full gaming days and recharging it is super fast. Love that I switched to a cordless mouse. Definitely recommend it!! If you’re doubting it..just do it!! Literally game changing

Transitioning from the heavier basilisk X Hyperspeed and Ultimate to this was so unexpected. I flick the mouse faster than usual and it tracks really accurately. I do miss the adjustable scroll wheel and extra buttons if you don’t count the right side.

I love this mouse. It fits my hand perfectly. The lightest mouse I have ever used. After using it I don’t want to use any other mouse. It also helped me a lot in gaming, especially shooting games. I highly recommend this mouse for anyone.

This is tied for best gaming mouse on the market for good reason. The tracking is very good, and the feet on the bottom of the mouse are smooth for any type of mouse pad. The dock is also a nice accessory on my desk. It is also very light in weight.

Feels light, super responsive, side buttons are positioned just right to be out of way but still usable. You can use all 4 side buttons if you want took me a lil to get used to but it was a quick to get comfortable. Great for finger tip grip/ hybrid palm/claw grip.

Great product! I've the versatility of being capable of being wired and wireless, holds charge for about three days but if you put it back on it's station after you're done it shouldn't be an issue.

Mouse is lightweight and very sleek looking. Had a hard time choosing between this and the Basilisk but went with this for the cheaper price point as well as the weight. Overall, I prefer this over the Basilisk and am extremely happy with it.

Loving it , the color, the feel, the whole vibe. Amazing customer service

I purchased this for my friend for his birthday and he says he loves it. He recently just got a pc for gaming and he says he likes the lightweight wireless mouse. (I bought it for 100 dollars)

Its a good light weight mouse and has long lasting battery

This mouse in incredibly lightweight and accurate with the lowest latency you can get while also being wireless. If you are looking for a mouse for FPS gaming look no further than the Razer Viper Ultimate. The included charging stand is incredibly nice as well.

Coming from a g303. I've hated razer for years as every razer product ice bought has broken. This mouse has had no problems for me. Battery lasts forever, 0 latency. I'm a logitech guy. I prefer this over the g pro because it's slightly shorter.
