Razer Viper 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 keep coming back to this amazing mouse.
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.

Great mouse for gaming
I like the design and feel of this mouse. It is not heavy. The design is also comfortable for my hand. The button-clicking feeling (clicky tactile feedback) is excellent. The programmable buttons work well with its software on Windows 11. The software auto-switches the mouse profile based on the game I am running. The macro functionality is flawless so far. The mouse feels very durable but time will tell me how much durable it is.

One of the best wired mouses out there!
This mouse is really good especially for being wired. It is a really good mouse and it literally makes your aim better. I clipped 2 unreal players in a row on fortnite with this mouse. The only reason I’m returning this mouse is because it being wired isn’t really comfortable for my gaming. That’s why Im switching to the Asus harpe aim labs edition which is wireless and lighter. But overall this a really good looking and performing mouse, and for being this cheap it really is high quality and worth your money. It is a good choice for gaming and the sensor has really accurate tracking for insanely improving your aim. The scrolling isnt the best but not the worst either. Because this is a wired mouse you don’t have to worry about battery life so its really convenient.

This is my main mouse.

Definitivamente es uno de los mejores mouse del 2019, top 3 sin discusión y en muchas áreas el #1Por donde lo veas este mouse es excelente, calidad de materiales, construcción, sensor, switches, forma.Se adapta mucho mejor para claw grip y fingertip grip aunque tambien podrías palmearlo si tu mano es pequeña.Pros+Buen cable, no es el mejor del mercado pero no tendrás ningún problema.+Los feet/skates son bastante buenos, igual no los mejores del mercado podrías mejorar con hyperglide pero tampoco es mucha diferencia.+La forma es muy segura, es decir, adaptable. No incómoda en ningún lugar y se ajusta perfecto a claw grip+ El peso para mí punto de vista es perfecto 70gr+Los clicks son suaves y sin pre travel, Tienen ligero post travel pero no afecta en nada. Fenomenales+Construcción excelente calidad, los grip de los costados muy bienCons+Software es pesado y solo lo debes utilizar para configurar lo que necesites y después borrar+Los feet pueden mejorar (esto si te pones muy peaky)+El precio es elevado+Un poco más de rgb no le habría hecho daño, finalmente es configurable+Los botones laterales están un poco atrás, si los usas muy muy seguido (para leaning en R6 o PUBG por ejemplo) será incómodoExcelente mouse realmente lo mejor que hay ahorita
