Customer Ratings & Reviews

Awesome, lightweight ambidextrous very responsive and fast. Optical switches are amazing, i wanted to the wireless but that one is very expensive for 50 bucks awesome

An excellent mouse for the price, lightweight, accurate, and the fastest clicks you can imagine. No really the viper only lacks in one major aspect and that's build yes plastic is the go to for most manufacturers but it wears out fast.

Very light weight, great for FPS gaming and also supports for both hands, no matter if you are a righty or lefty this is a great mouse for regular use or gaming.

Razer back at it again with this high end light weight mouse. It’s a joy to use while gaming call of duty. Never disappoints and always tracks perfectly.

The mouse is great, I've been using it continuously for 2 weeks throughout the working at home. It is great for both playing games and general productivity.

Perfect replacement for my old one. Clicks are very satisfying and it rolls well. RGB isn’t too visible but it’s pretty regardless :)

The mouse is very good and light but after not too long it started to creek and it got very annoying fast. Overall the mouse is good, very light cable and glides well but built very cheaply.

Really like this mouse. Ambidextrous design and very lightweight. This mouse glides across the pad with ease and the buttons are solid. What else do you need?

Great shape and weight, switches are just fine provided you check the serial number. My left side buttons are a little uneven however but otherwise perfect.

Honesty I really like the shape of this mouse but it has one flaw that made me return it. The side buttons were hard to use and if you play games like me, side button accessibility is a must. I think that if you use this for normal browsing then its a good mouse.

Razer has always been THE brand for gaming. The pros of this mouse is the weight and the new cord that doesn’t drag. However, other than that, it’s rather decent for the price. Nothing much more than the other competitors.

beautiful, light, and useful. not for mega hardcore gamers that need more than 5 buttons but for the rest, it's a clean and cool solution.

I got it on sale for about $60 in total so I felt like it was worth the buy. The price, $80, is a bit over price but the weight makes up for it. I recommend it.

Good quality build, works perfect, optical sensor work good, great price, overall I'm very happy with this, will buy again when I need another one.

This is an excellent, light, quick, and very precise mouse for fast-paced gaming. The Razer software to go along with it is good also and does not get in the way. Even with the small stature of the mouse it has several programmable buttons and the mouse roller is light but tactile... it is not as clicky as some of them which is very nice. For example some of the older Basilisk mouses had a much clickier roller/wheel which made some games actually difficult.

really fast and clean, nice fit size overall and perfect

Works flawlessly, the weightless feel of it and an overwhelming amount of keys on the mouse makes it really nice. It's not worth $80 though.

Simply a great little mouse that performs well. Very responsive, the scroll wheel is nice and snappy. The side mouse buttons can be a bit awkward to hit since it can be tough to press them without moving the mouse, but that's OK.

My son loves this mouse. He said it is very easy to use and also lightweight. Great purchase, plan to buy more for the rest of the kids.

I thought every mouse was the same until I got the Razer Viper! This mouse has changed my life and has made me the pro gamer that I am today!
