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

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

it has everything you seem to want out of a fps mouse , lightweight yes, fast clicks yes, ergonomic shape yes, what more can I say, the only reason its 4 stars is of course because of the virus-like razor software that gets installed on your PC when you connect the mouse automatically.

It’s very light and it really helps improve your gameplay. If your a valorant player like me, this mouse will be perfect for you.

I havent had a Razer mouse in a while. I left-hand mouse and a while ago switched to Logitech ambidextrous mice. I had a G900 for a while and got a G903 with the Powerplay mouse pad, and it was fine until the battery stopped holding a charge and I found out they apparently dont sell the battery separately. So I figured Id go back to wired mice. Poked around for a good ambi mouse and this kept showing up. Was on sale for $40, figured it wouldnt hurt to try. Sure enough, it surprised me. The butt of the mouse isnt as tall as Im used to so its taken a bit to get used to having a different grip, but it works and didnt take me too long. The buttons feel good and I havent had an issue getting used to them. Biggest problem I have is the DPI switch is on the bottom of the mouse, which is kind of pointless, but I rebound the side mouse buttons opposite my thumb to be sensitivity up/down buttons. Not quite as convenient as the Logi G900/G903, but better than having to flip the mouse over. I was concerned about how the RGB would work as my home PC setup is... unique. I have a Dell dock that goes between my work laptop (Win10) and my personal laptop (mostly Ubuntu, I boot into Win10 for video calls with friends), and then I use USB switches to switch over my Win10 gaming PC. Unless a mouse has built in memory my profiles always get royally messed up, and theres some confusion around this mouses onboard memory... So, for me, its totally fine. Button layout (as in left or right handed) and DPI settings stay on the mouse as it moves around between computers. RGB definitely gets lost, but weirdly the way the linux tools set the RGB ... it stays at whatever those tools set it at until Razer Synapse starts? Once thats running it takes back over, but ultimately... it works for me so whatever.

I like everything about the mouse (size, weight, feel) except the main two mouse buttons. They are too stiff for my taste. I have to work too hard and often times dont get a correct double-click. For an all-day productivity mouse (in addition to some light gaming), this might be a deal breaker for me. Update: After giving it more of a chance, Ive come to like it. Ideally, the buttons would be little less stiff, but its not bad and Ive gotten used to it.

This is one of the best Razer mouses Ive ever used and Ive been using Razer products for a while now. Really good scroll wheel, grips feel awesome, and really good mouse buttons, the only thing that I wish was better was the Left And Right click when you press them they arent really that tactical and clicky enough for me, and I wish Razer added some sort of Hyper Glides, G.Skates something along those lines, but its not that much of a problem.

Pros: -Lightweight (Amazing weight without the honeycomb design) -Great Grip (Comfortable) -Optical Sensor (Faster Clicks) -Dpi button on bottom (No accidental Dpi switches) -Great Clicky sound :) -Great price for the amount of tech youre getting ($) -Bendable mouse cord (wont get caught) -Side buttons on both sides (I was worried about clicking them by accident at first, but they do not stick out enough to press them) Cons: -The optical sensor does take some time to get use too -Side buttons do not protrude out as much as other mice (So again it takes some time to get use too) Conclusion: 5 out 5 Razer knocked it out of the ball park with this one. I would recommend this mouse to anyone, especially gamers.

Ive been on the quest for a light mouse. Ive had a few now, with the last being a Logitech G305. Great mouse overall, but not without its caveats. This one is the lightest and doesnt suffer from a hit in construction or feel as a result. Its vaguely shaped like a Deathadder with an ambidextrous twist and a slightly shallower profile. Comfortable, incredibly easy to maneuver, and the cable delivers on its drag-free promise. The switches are responsive and the buttons have the perfect level of tension. The sensor is smoooth and accurate. I have a 144Hz refresh rate monitor and the cursor is always where I want it. Aesthetically, its a nice touch that the Razer logo is entirely hidden until its illuminated, giving you a stealthy, branding-free look if thats what youre seeking. Id highly recommend this mouse and am very impressed by what it delivers at this price point!

The stock feet on the initial batches were terrible (really slow and sluggish). Per Razers rep on Reddits r/MouseReview subReddit, the latest batches are being made with quality PTFE feet. If you happen to get one from the earlier batches, some excellent after-market replacement feet are available (e.g., Hotline Games Competition and Tiger Arc 2). The rest of the mouse more than makes up for this minor, fixable nuisance if youre a claw gripper with medium-to-large hands. My main for the foreseeable future. It feels like a lighter Logitech G403, but without the back end hump that many, including me, find annoying. Other mice I own: Glorious Model O and O- Logitech G Pro Wireless Zowie FK2 Logitech G203 Zowie S1 and S2

I generally value Razers products. Markedly more than certain social media negative group-think regards them. And I do like this product, generally speaking. The sensor is amazing. The ergonomics are perfect for me. The consistency in the data transmission rate is vastly superior to other competitor brands. All in all, it would be a fantastic mouse. However. This is one of their flagship models, and boasts the low-latency optical switches. Unfortunately, the alternate-click switch gets stuck on, on occasion. Its an intermittent issue so very hard to demonstrate and troubleshoot, but manifests itself with enough frequency to be fairly irritating. It has also progressed with time. I discovered this within a month of purchasing it, and contacted customer support. In the past their customer support has been extremely helpful. RMAs and warranty returns have always been forthcoming and never left me with a moment of down time. Even granted an entire replacement mouse for a deathadder, whose only issue was the adhesive wearing off on the rubber thumb pad on the side. This time, after a round robin with the customer service rep, repeating myself until they finally comprehended, their solution was to have me send the mouse in, and wait... **Mouseless**... Until they shipped a replacement. I suspect that because the issue is difficult to demonstrate and present, they were suspicious that I was attempting to scam them out of free hardware. Absolutely infuriating. I did not send in the mouse. Which has continued to progressively worsen over time. Editorial note: I imagine the customer service reps reaction to closing the ticket with no response from me, after not having received the faulty product, as smug satisfaction for having saved the company from a fraudulent RMA.
