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

The viper has been quiet good for now. Sadly the size of the mouse is not my type but Im in love with the weight. The only thing I just hate is the software. Theres so much stuff on it and one thing that just made no sense at all. Is making the buttons on the right side appear as extra buttons. They just repeat themselves in the software. Plain stupid. I would probably give this mouse a 3.9/5

Im not good at knowing what makes a mouse good I just know that I went from a g300s mouse 80 grams light small and very comfortable after a year I decided to retire the mouse and i bought a g502 thinking moar money equals better but the mouse was heavy not so comfortable and lacked the small form factor I proceed to look for a new mouse so i looked around the web I found final mouse I thought oo nice but i saw the price and packed my wallet than i saw the model o i assumed it would be great but i saw the holes and decided not to opt for that finally I came across this mouse on release and instantly liked its very basic look and pulled the trigger my hand is 19 cm long and 9 across so for me the size was no issue overall my only problem is long use of this mouse tires my fingers out but otherwise im happy

Its a little large for me in terms of the mouse. The keys on the right side are hard to get to, I guess Im not used to it. Would have preferred more keys to the left but I guess this is for both left and right hand users. Overall works pretty well.

I like it for gaming and the side buttons are very easy to press. Mine said that it would be in stock on feb 10 and that it would come on feb 18 but it came feb 7 yeah you heard that right we even had the free shipping

Great mouse. I got this mouse cause I wanted something semi light but not to light. And I didn’t want the look of the cheese grader holey mouse that’s the new trend. I just dislike that look. This mouse is amazing! But the software with it still has flaws. Even tho you can finically save profiles to the mouse and not have to use synapse the profile still doesn’t save the lighting profile unless you select it off. It always reverts back to cycling. This is a big annoying factor for people who match their setups. So I keep it off so it won’t clash with my setup. So I basically paid for a rgb feature I can’t use because I don’t want synapse on my computer as it uses to many resources for me personally. Just something to factor in the total experience of this product. The mouse itself is amazing however. Super light cord great feeling buttons. Light while not being to light and doesn’t have that stupid hole look. If you can deal with the software issues it’s a winner. I spoke with razer and told them and they are working on making it save the profiles including lighting to the mouse so hopefully that will be a thing soon. Synapse still is garbage. And I will continue to say that until you can save lighting profiles on keyboards and mice without having to have the software open. Just overall ignorance on razers part. We have been complaining about this for years. Mouse overall is great tho. Just the fact razer shoves synapse down your throat is stupid. Main reason why I don’t use rgb. I refuse to have that crap open

this mouse is perfect if youre looking for something better than a generic one but not necessarily something crazy complex or advanced. if you like the feel of an ambidextrous mouse, this one is perfect - not too big, not too small, fits comfortably in either a claw or palm grip. the height does take some getting used to not because its taller or shorter than other mice but because of the placement of the highest point. again, its not uncomfortable, just different. the software that is required to program keybinds to the buttons and set up profiles is not as annoying as some reviews would make it seem but it does take a while to load up when turning on your computer. nothing unbearable, though. overall, i am quite pleased with my purchase!

Im satisfied with the design, its compact, the side buttons are somewhat inside the case. Actually all the buttons are low profile which helps a lot. The buttons are of high quality. Mouses responsiveness is also pretty good, indicating a good sensor. The mouse is lightweight and it feels pretty good. At first I thought the mouses skates are lacking but not anymore. They feel on point, I just had to adjust the DPI.

Its very very light. Design is useful, materials are soft and nice.

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 cant say enough good things about this mouse. Its 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 wasnt 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 dont 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 isnt 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 dont need to - its 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 wont 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 dont 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 isnt 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.

I need click consistency and perfect control, so far its all here 100%. No cliche here, if you were already dangerous in game this mouse will make you more so. If you are a beginner this mouse is a solid must. I would have loved to have this mouse 1,000s of hours ago in pubs. I think I will gladly wear this thing out until the next best model comes out. Recommend. P.S. I almost always find some weird little quark in a mouse or keyboard that wasnt in the sale ad or photos, a quark that really annoys me. So far this mouse is quark free lol, no lie. Good stuff.
