RazerViper Ultralight Ambidextrous Wired Gaming Mouse: Fastest Mouse Switch in Gaming - 16,000 DPI Optical Sensor - Chroma RGB Lighting - 8 Programmable Buttons - Drag-Free Cord

I have gone through a handful of really amazing gaming mice in the last few months including the Glorious Model O and Model O-, the Zowie s2, Logitech G203 (amazing at $25), and this Razer Viper. I can't say enough good things about this mouse. It's incredibly light and glides incredibly well on my mousepad. The grips on the side are a great feature. They make other mice feel slippery once you get used to them.For me, the one minor thing that I would change about this mouse is the buttons on the side should stick out a little more. They are not in so far as to cause issues or misclicks, but I like to really feel where the mouse buttons are at all times. I do like the big thumb buttons on the Zowie S2 over these.One of the best features of this mouse is the scroll wheel. I use the wheel button in games frequently as I hold my mouse with 3 fingers on top (middle finger resting on the scroll wheel and ring finger on right mouse click button). The button press and tension is perfect - not too stiff, and not impossible to click at will. The scroll wheel movement is super smooth and tensioned where I like it. It also has a great rubber grip with a low profile texture that holds your finger very well.Button clicks are tuned very well on this mouse. Pronounced enough that you get a solid click with a bit of travel. I have never had an instance where there is an accidental double-click or a time where I needed to click quickly and it wasn't able to deliver. They feel great.The electronics in the mouse are some of the best available. Button switches are laser actuated so no delays or debounce issues. The sensor is spot on.One thing that I love about this is that you don't need the software to run it. I hate adding bloatware on my machine and yes, sorry Razer, I have uninstalled synapse and every other driver software that isn't system critical so I could save some performance when I run games. You can config this mouse with Synapse if you would like, but you really don't need to - it's plug and play. Keeping Synapse around will allow you to get the sweet RGB logo throbbing in sync with your other Razer peripherals. Otherwise, there is a DPI button on the bottom and an indicator light to let you know what your setting is and you are good to go.I did end up replacing the skates on this with Hyperglides. Hyperglide does not make drop-in glided for this, so I had to cut my own using the originals as templates. I used a very sharp exacto knife and traced the cut around the outside of the originals carefully. I used the bottom skate from a hyperglide cut for Zowie s2 and the top glide cut for Razer Death Adder. You could use the Death Adder glides, but the bottom one won't match exactly with the stock viper because there is not quite enough material. The curve is the same so, in a pinch, you can drop it in, but it will not match the stock exactly. Once I cut the shapes to match the stock glides, I beveled the edges and wet sanded them smooth down to 3000 grit sandpaper. I also used a little rubbing polish, but I don't think it was really necessary.The cable on this is close to a paracable with lots of flex. At some point, I am going to upgrade to a hand made paracable, but for now, the stock cable isn't bad at all. Removing the shielding from the cable will give it more flex, but manufacturers are not allowed to do this per USB standards, I believe. Just a heads-up, if you decide to crack the Viper open and replace the cable, I have read it does not use a standard JST 2.0mm 5 pin inside the mouse. I believe it uses the smaller 1.5mm JST.Bottom line is that this mouse was designed with input from pro gamers and the end result shows. I am not normally a fan of Razer products and like the smaller gaming brands like Glorious, Ducky, Zowie, etc. but Razer is one hell of a company. They understand what it means to be design-led and always marry looks, experience, functionality. The packaging on this is your standard amazing razer packaging and the whole thing, start to finish, is worth every penny. Great job on this one, Razer. You got me this time.

It's a $70 mouse as of this writing. There is a difference... wow there is. This is my daily driver for work.TLDR: Proper gaming peripheral designers put substantial thought into how the user will use their products and when they do an amazing job you get a mouse like this.You can read lots of gushing glowing reviews about this product but let me add another perspective to the conversation. For use in an office setting this mouse has been reliable and consistent with its performance. There have been no issues with build quality. No need to worry about a button some coming unset and having to push on just the right spot to get it click back into place. The cloth cord eliminates the dreaded "sticky plastic usb cord" phenomenon that we've all, well most of us at least, have had to contend with.Also I'm a big fan of being able to adjust the sensitivity of the mouse on the mouse and not in OS. Also I'm a big fan of the light weight but also solid feel in my hand.Why not wireless?I switched to a wired mouse for stability reasons. We live in the age of dongles and garbage usb docks and hubs. The manufacturers of these critical pieces of hardware have produced for the most part products that either flat out don't do what they claim to do, do what they claim to do but have stability issues due to poor thermal management, or are too simple in functionality and you don't get that many more ports out of the dongle. I bought this mouse to address the second scenario, thermal performance of my usb dock. The wireless mouse I was using would start to glitch and behave erratically on me as the dock got hotter. Not this mouse.If you can afford it I wold recommend buying this mouse. Also show some love to your mouse and get a proper mouse pad or gaming mat.

I wanted to work on improving my aim and so I bought this mouse since it was very lightweight which means less force to start and stop moving it. I can definitely tell the difference, even just using it for work I could tell there was much less strain on my hand/ wrist. Previously I was using the Razer Lancehead due to its good reviews on reliability and I used all 4 side buttons for extra functionality at work. While I still have my Lancehead which has been reliable I wanted something better. I can tell the feel in the hand with the Viper is so much better even though its still ambidextrous. I had just gotten used to more of a claw grip due to the mice I have used in the past but the Viper really works for more hand styles. With my small hands the feel is like an in between a claw and palm grip but I can tell it would be good for either. I can tell the main issue with the lancehead other than weight was how flared out the back was. Another good thing about the Viper is the cable it comes with. Due to the limited space on my desk I'm forced to have my JDS Element 2 above my mouse mat which previously would move your mouse a little if you let go because of the strained against it. The cable the viper comes with allows more leeway before it gives out. Side grips are also a benefit and I have not had any issues with it pealing off or anything. Definitely give this mouse a try.

The mouse is very responsive. The RGB Razer logo light is cool. You can't see it when you use the mouse though. That pretty much is almost standare RGB mice.Feels great on the hand, and is very light. I'm a PC gamer and it's worth it. Good price.One other thing. The side buttons are difficult for me to use. Poor position is a problem. I don't use side buttons, so I don't care.

this is the best an confortable gaming mouse that i have used ever, i recommended for the quality and price.
