Customer Ratings & Reviews

Not bad! Works really well with my gaming pc. The wireless option is pretty good too!

Mouse is responsive. I don’t know if I got a defective cord on mine but it is double maybe triple the size of my other cords for all of my razer products. This thing feels like it’s going to start shredding apart with moderate usage…not good for a wired mouse. It feels like a hoodie drawstring. It bugs me to no end that it doesn’t match ANY of the other razer product cords I have and those are all identical aside from color.

I do not regret this purchase. Great gaming mouse!!

I like the mouse it fits my aesthetic just wish it was a little more weight to it. It kind of feels cheap to me.

I purchased this mouse to replace my Epic Naga Chroma, and it’s far better for my play style. First off, it’s ambidextrous, so it fits any user. It’s extremely lightweight, at 69 grams (nice) and glides across my mousepad with ease. It’s very responsive because of its optical switches, and has a very clicky mouse wheel, which I enjoy. The clicks are very satisfying, as they aren’t loud, but aren’t too quiet. The cord is the lightest braided cable I’ve experienced, so it doesn’t weigh the mouse down. Mouse overall looks amazing, feels amazing, and responds to everything.

This is the one. Desktop, office, and power users: don't shy away from this just because its marketed at gamers! Pros: Matte finish. Feels great in hand. Just enough grip and doesn't get slippery if you hands are wet/sweaty. Tasteful RGB. Slow smooth color transitions by default. Very light. I did not realize how much weight contributes to the enjoyment of using a mouse. Clicks are soft and quiet. Office approved. Button underneath for changing dpi. You can totally use this mouse without installing software. Thin and flexy cord. I've always preferred wireless, but this cord is so light you wouldn't know it wasn't wireless. Ambidextrous, however, I have not had any issues accidentally hitting the right side buttons. Not once. The pads. This thing glides like a dream. Scroll wheel is solid. I've passed on many of the popular mice out there because their scroll wheels felt loose/wobbly. Has little grips on the wheel for traction. Cons: None. All hail Razer!

This is a solid mouse that turned out to just be too awkward of a shape for my hand. It's very light weight and was a perfect size for a small to medium hand. I am used to a palm grip style and occasionally hybrid grib but unfortunately because of it's shape it forced me to completely change my grip style and as a result I was unable to utilize the side mouse buttons the way I wanted to. This was not a flaw in the mouse, Just my own personal preference in grip. The optical mouse buttons have a crisp click that are responsive. No complaints. The sensor is great. Side mouse buttons were clicky although slightly small for my taste. If you like ambidextrous shaped mice that are lightweight. Maybe give this one a try. If you are looking for an ergo design, I would try something else.

There are a ton of ultra-light mouse out there which are only focused for competitive fps shooters. The same goes for razer, it ultra-light and ambidextrous, however the hyper-shift functionality the mouse has makes it even better. I used to use a gaming mouse with several buttons on it but it was just to heavy to be competitive in any sort of fps. The Hyper shift functionality allow me to double the functionality of every single button. For example the two side buttons basically turn into 4 buttons with the use of hypershift. So with hypershift I get a total of 8 more buttons (this includes scroll up and scroll down). Which is awesome when it comes to shooters like Battlefield 5, Squad and Insurgency sandstorm where you need to have more than just the side buttons to really get an edge in the game. Build quality wise, its very well built, no rattling of any kind, the cord is very flexible and soft. Its as if it's not there. The only downside which goes away after a few hours of use are the mouse pads, they kind of have to be "broken" in. They were rough at first but after a few rounds of gaming it became smooth. However I use a set of aftermarket mouse feet so I removed them and use the ones I installed and the mouse is basically perfect in my book. The mouse is best for claw and palm/claw grip, unless you have extremely small hands a palm grip is not ideal for this mouse. One thing I want to point out many of the popular light weight mice are about 10 to 15 bucks cheaper than this one, however for me the hypershift functionality more than makes up for the slight increase in price. If you want a top grade gaming mouse that also offers great functionality choose this. There is a wireless one coming out, however it is nearly double the price of the wired, the only advantage you are getting is slightly better mouse pads and wireless capability. If you can live with the wire, this one is a great deal.

Get it on sale. The sensor is one of the best you can get if you look it up. The cord is light but durable. It doesn't have the honeycomb holes in it which is a plus to me. Nice and lightweight to boot so perfect for fps. Or a large mouse but not too small either and I have long fingers. With longer mice you get more weight.

Take this review with a grain of salt, because I'm biased for having only purchased 10-20 dollar non-name brand mice up until this point, but I gotta say this mouse is great. I don't know much about mice technically, all I can say is it's a much smoother experience than what my previous 15 dollar one could do. Plus it has different colors to represent what DPI setting you're at so you know which is your preferred in an instant, and it's cord is really loose in a good way. My wire situation is abysmal I admit, but even still the cord always has this innate amount of slack which means I'm never working against the cord to, say, aim in an FPS. The only downside I can see for someone is the software included with all of Razr's hardware. I'm not bothered by having to wait a bit for it all to kick in on start-up, but maybe other slower computers might have a harder time with that? I couldn't say though, I've not tried it on anything other than the one computer I have. This is all to say, I think this mouse is definitely worth it for the price. If you've been going cheap on mice, this is a good one to upgrade to that isn't near 100 dollars, but absolutely makes a difference in experience.

I've been a Logitech fanboy for mice and Corsair for keyboards. However, after using and owning the Razer Huntsman Elite Keyboard, the optical switches are no joke. When the Razer Viper came and it had optical switches, I had to try it out. Coming from a Logitech G703 with Powerplay Mousepad: Pros: -Responsiveness: I don't know what it is, but the responsiveness of each click felt significantly faster and you could definitely notice this when shooting a pistol. I thought it was a gimmick and kept switching between the G703 and Viper, but no, the Viper definitely felt like it was registering faster. Saw a test on YouTube about the MS and they showed the Viper being faster I think it was 189 vs 228/238 something like that. -Cord: I was worried about switching from a wireless mouse to a wired mouse, but after use, it felt the same as a wireless mouse. The cable is no joke; they definitely did a good job at making the cable feel nonexistent. -Speed/Control: This mouse is very good for claw grip. Not so good for palm grip if you have big hands due to the fact that it's lower than average mice in height. However, it's like cars; the lower it is the better speed and control you have. It definitely has that. CONS: -Ergonomics: I actually prefer the hump on the back of the Logitech G703 over this mouse for ergonomics. Needless to say, I'm also not a fan of ambidextrous mice. -No onboard memory (which probably helped kept it low weight). Need Synapse. The reason why I hate this mouse is because I'm having a hard time accepting the fact that Razer actually made a mouse better than Logitech for gaming. Logitech will probably make a Optical switch eventually but currently, they do not. I still prefer using Logitech mice for everything else, but for gaming, there is no question: Razer Viper is the best gaming mouse today especially for FPS games hands down no hesitation.

I'm left-handed, and most of the mice available are right-handed. The mouse that came with my desktop was one of those mice. I could use it, but it wasn't as comfortable. I decided to purchase this Razer mouse because there are buttons on both sides of the mouse, and they can all be programmed. After I purchased this mouse, I decided to return the HyperX keyboard I had purchased at the same time, and I purchased a Razer Cynosa keyboard. The colors change on both the keyboard and the mouse. This gives it a more seamless feel. And you can customize the colors and patterns. I haven't done much with that, it seemed a bit daunting. There's a DPI switch on the bottom so you can adjust the precision of the movement.

Light mouse optomechanical switches prevents double clicking Flexible cable Scroll wheel feels fine accurate sensor ambidextrous mouse Has left and right mouse buttons The mouse is good, but the shape of mice is not for me. This is a personal preference.

Was pleasantly surprised with this mouse. Even though its ambidextrous, having side buttons on both sides isn't as annoying as I thought it would be and it's actually not inconvenient at all. Besides that, the mouse is incredibly light and I like being able to change the DPI and the colors on the mouse. The clicks are quite loud, but nothing too bad if you have a headset on.

Pretty much the best mice you can buy. It is lightweight which is good for shooters. It is also good for daily activities. It feels great and very quick and responsive. If I had to do it all again and I wanted a top mouse, I would get the wireless version and pay more. This one does the job tho. The cord is perfect and does not get in the way. Top notch product

I've been looking forward to acquiring a Razer Viper for months ever since seeing it for the first time and holding the mouse with my own hand. Unlike the current crop of Razer gaming mice, the Viper bucks the trend of ever larger sized mice to accommodate users with over sized ham fisted paws for hands. Not since the halcyon days of Razer's Diamondback and Copperhead has a Razer mouse been comfortable for me to hold using the claw style grip. Almost all modern Razer mice have a tall bulbous hump on the top side of the mouse starting from the middle and working its way to the back end of the mouse. Not so with the Viper. The Viper's dimensions and shape are lower profile and left/right side symmetric like the Diamondback and Copperhead designs from a decade ago. Combined with the Viper's light in class 69g curb weight (not including weight of cord) this mouse is not only comfortable to grip but also not tiring to push around as it requires very little physical movement to make the mouse pointer move quickly in RTS type games. As it stands the Viper has full Razer Synapse driver support, a 5G sensor with maximum 16k DPI sensitivity, on the fly sensitivity control button on the bottom with LED indicator, built in settings profile memory and new in class optical switches for button 1 and 2. Button 1 and 2 appear to respond very quickly to input clicks with no observable ghosting or repeated inputs despite only a single physical click. The only downside to the Viper is it's one of the most expensive corded Razer gaming mouse sold by Best Buy. However if you don't have large ham fisted paws for hands and prefer Razer gaming mice, BB and Razer kind of have you over the proverbial barrel. I bit the bullet and got a Viper and haven't looked back. Be aware if your computer does not already have Razer Synapse software installed, this package can take awhile to install once downloaded.

A decent mouse for FPS games, although there are a few major drawbacks that keep it from being a good, lasting product. Pros: The mouse has a good ambidextrous shape, although just a bit long, which makes it difficult to fingertip grip with my hand size (19x10cm). Flexible cable. Good sensor. Very lightweight. Plastic feels very sturdy. Cons: Side buttons are a little awkward in their shape and positioning. RGB requires Synapse software to be running. These last two complains were the only ones I could come up with for long time owning this mouse and I thought I could overlook them due to how much I like the mouse overall. However, there is now one thing which will keep me from using this mouse. The fatal flaw of this mouse is the built-in rubber side grips. These used to feel great but have now started to peel and deteriorate where my thumb holds the mouse after 4 months of daily use gaming. Due to the permanent grips not being very durable, I do not recommend the Razer Viper and I am now in need of a replacement mouse. This is sad because before this point of failure arose I did like using it.

my new favorite mouse! pros: - light - 4 additional buttons (2 on the left and 2 on the right) - nice greap - ok wheel - 3 DPI profiles (configurable) - can by sync with other razer stuff cons: - price, I got one with sale - razer software - hard to configure lights on mac

I’m impressed with this mouse. Optic clicks and very light mouse with ease to move. This is great for fingertips users or claw users but not for palm users. Blaze fast with 16,000 DPI. I am comfortable with between 400 and 2000 DPI. The cord is flexible and soft so you won’t notice tangle or something in your way.

Very light mouse and has an incredible price. Feels better than some of the best high end mouses such as the cape town. Would recommend it to anyone who is looking for a light clean mouse. It also can light up to whatever you like it to and has many options.
