Razer Viper Ambidextrous Mouse 16,000 Dpi - Optical Sensor - Chroma, Black - Windows, Medium

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.

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

Here's a bit of a dramatic history lesson; if you don't care for it and what the raw details, skip ahead.-----------------------------------Anybody who grew up when competitive gaming first started booming knew there was only one thing that truly kept it all together: a compelling, new-age, tailor-made passion.In the mid 2000s, Razer got widespread attention with the releases of their Diamondback and Copperhead mice. They were their first mainstream products, and man did it feel surreal to experience what would be known as the first gaming peripherals. The color lighting in motion, the clicks, the premium feel of something engineered for us few (at the time) gamers was something that I'll always thank Razer for. Logitech was still making exclusively office supply mice, and the closest thing to gaming mouse was the Microsoft Intellimouse 3.0.They took the first step forward, because they knew that what was about to come was based on a fiery passion that every user reading this review knows by heart: competitive gaming.Now I'm not going to sit here and say they reigned forever. Logitech, Zowie, and Finalmouse have been IMO dominating the market for competitive mice, and I say that with no regret. I'm a personal advocate of the Zowie ZA series, but I've used all mice from the Sensei/Kinzu to the Deathadder 2013 to the Logitech G Pro. The Razer Viper puts the company finally back where it belongs.-----------------------------------I won't get into what you can get from their advertising. Let me explain how it actually performs in your hand:-The shape and weight works in perfect unison together. I personally didn't like the Zowie FK1/2 despite its praise, but I do to this day love the ZA11. I appreciate the contact at the base of my palm as a sort of pivot point, and I have my fingers operate the mouse with a claw grip. This mouse is a dream if you use your mice similarly.-The mouse wheel is by far the best I've ever used in any mouse. It has absolutely, I mean zero, wobble, it is extremely quiet to the point of being silent, the clicks are subtle yet firm, and the weight is just like the mouse itself: light.-The clicks, from a feel standpoint, are different. I enjoy the silent switches you find on silent mice, but I can understand those who like the Zowie style which is like a banging click that gives you strong feedback and assurance. They do feel mushy, I am not going to lie, and they will take time getting used to, because pushing them too hard is a thing, and I do have concerns about how long they will last. I am hoping my muscle memory will get adjusted from my Zowie mouse and it will actually turn out for the better. From the limited time I've used it, I do believe that with a softer touch, these will be something that I cannot get away from.-With the softer touch, I do feel a bit quicker on the clicks. The softer touch required to fully depress them makes your fingers feel a lot more nimble, which is awesome. Less strain, more gain.-The opposite side buttons are near impossible to accidentally press. I actually like having the option to do with ease so because extra binds are always something I enjoy. But if that's a concern of yours, drop it. For this reason, the hypershift keys are a godsend.

I needed an ambidextrous mouse since I'm left-handed so I have to always get a mouse with the two buttons on the left side and the right side the only issue with this mouse is the buttons on the side are so flush with the side of the mouse so it's hard to press them with my side of my ring finger and even using my thumb on the other buttons on the right side seem too flush. I ended up actually gluing pieces of plastic to make it a little bit easier for my hands to press those small buttons on the side.
