Customer Ratings & Reviews

I've been a long time Razer fanboy going all the way back to the original Boomslang ball mouse (somewhere in a box in storage and probably still works). I loved that mouse so much that I bought the optical version once Razer (the company) resurrected from ashes. Onto the new ultralight version of the Viper. I'm not an eSports guy so I might not appreciate all the features and honestly I like some weight on my mouse. I used to purchase mice with custom weights and always adding the max weights but recently I've been getting some of the lightweight wired mice. It does have a great grip, fitting my hand nicely with buttons easily in reach. I do like the optional die cut grip material they provide on a sheet that you can peel and stick to add texture. I really like this feature because it does feel like it gives me a better grip on such a light device. It does have a 30K optical sensor which makes it extremely fast but I personally will gear that down while I play the FPS games I usually play. One thing missing for me is the DPI on the fly buttons on top by the scroll wheel. Instead they put the button on the bottom... REALLY??? THE BOTTOM??? I play some FPS games that I like switching to a slower response so I don't overshoot my aimpoint. Putting the DPI switch on the bottom does not let me switch on the fly. It is rechargable and comes with a very flexible braided USB C cord for both direct plug in or you can use the USB adapter with the cable as a remote mount for the 2.4Hz dongle. I have yet drained the battery so the charges last a good while. The good part is if you do drain the battery you just plug in the USB A to USB C cable to the mouse and you can use it as a regular wired mouse while it's charging. I'm surprised that Razer didn't provide a dock for this mouse like the Viper Ultimate. There is no place to stow the USB transceiver if you toss the mouse in a laptop bag... easy to lose! Just ask how many transceivers I've had to purchase off eBay. My biggest fuss is about Razer Synapse software. I've mentioned in a few other Razer reviews that I really don't like Synapse. I had install issues with the software however the latest version installs much better than the previous versions that hosed my Windows install. I also don't like the fact that when I boot I always get a notification to install Synapse as the system recognizes the Viper. I have yet to find a way to opt out of installing Synapse. Don't get me wrong, Synapse has some nice features and allows you to customize the buttons on the Viper but I mostly use the default Windows mouse settings so it's just annoying at this point. I also have a problem with the current price point. At $150 there are other options available, even in the Razer line, that might be a better choice. If you are already in the Razer ecosystem or wanting to move to it the Viper V2 Pro would be a nice addition to your gear. If you like some of the ultralight wired version mice then the Viper might be a good add for you as well.

The tracking and speed is incredible, but i found the mouse too small for me. It was between this one and Logitech pro super light if u got smaller hands id recommend this mouse for sure

It was heavy compared to my regular viper. Got a model o- wireless instead. Cheap quality on the viper also no leds. Lighter as well

Loved the mouse while it lasted. The thumb side button broke after 3 months. It is a great mouse but I think has durability issues. Now I’m out $150. I’ll stick with Logitech from now on.

Razer - Viper V2 Pro Wireless Optical Gaming Mouse The first thing to say about Razer V2 Pro is good grief is this thing light. I have always preferred a lightweight mouse. So any mouse I have had that came with weights I have never used them. But the Razer Viper V2 Pro is at a whole other level here. And why is that a preference for me, well it’s just faster for gaming and less fatiguing. And I can imagine if you travel with it you will love it. This is the mouse I would have made if I was designing one. It is very comfortable not just for gaming but for any use. The form factor is very much like their famous DeathAdder Pro which is really a legend among gaming mice. So if you like that feel it is mostly here but without the cable and weight. I have been on the same charge for a week of all day use. Razer claims it takes four hours to charge a low battery. The single LED on the top will blink when the battery gets low. I like that it is not overdone with buttons I will never use. And the buttons and mouse wheel are up to Razer quality. If I had one complaint about this mouse is that maybe the right and left buttons could be a bit quieter. It's not anything you would hear gaming but it might be a problem in a crowded office. Similar to why you should be very careful with what type of keys you would use on a mechanical keyboards if you are using one in an office. I am hoping it will quiet down with use but it is not enough to detract from what makes this such a great mouse. Along with the mouse you get a high quality USB type C braided cable, mouse grip tape you can apply and a neat docking adapter you can put the wireless receiver in if you have any connection issues. I didn’t need it but it's nice that it was included. I don’t find it an issue but to change the DPI setting there is a button on the bottom of the mouse. That could be a deal breaker if you are a gamer who switches DPI settings in game. The one LED light on the top indicates which DPI mode you're in. I typically don’t switch DPI settings so that isn’t an issue for me. And yes no RGB which Razer is famous for won’t be found on display here. I was never a big fan of RGB on a wireless mouse as it will drain the battery. Also other than telling me the DPI setting I never understood the value of RGB on a mouse. For a keyboard RGB makes great sense, but I am not convinced of the value of RGB on a mouse, especially on a wireless mouse. For full disclosure here I did not install the Razer software. As soon as I plugged it in the software came up to be installed from the Windows store. I elected not to install it. I use a KVM switch at my desktop to switch between four computers all day and I preferred to not install software on them. The good news is I don’t see any functions I need that require the software. That is perfect for me and another reason I am very much liking this mouse. If you're looking for RGB this is not it. If you are looking for a great wireless gaming mouse, heck just a great mouse overall I can highly recommend the Viper V2 Pro. And good grief is this thing light.

Replaced multiple times and same issues with all. Mouse/PC unable to connect with dongle for use in wireless mode. Firmware and utility pairing software cannot detect dongle so no ability to troubleshoot.

Doesn’t pair with dongle anymore. Only works when wired

This mouse is a coin flip, I forget the process but if you don't turn it on in a specific way, it will brick the receiver. Then you can only use it in wired mode. Youtube problems for this mouse. I bought the pro superlight in red when I went to replace this mouse, it's been so much nicer to use and plug and play.

Super cheap feeling mouse. Doesn’t even feel like a high quality mouse. I feel like this mouse should only be around $50

Software seems like my pc has a virus. Will not get razer again.

i had two of these, the usb dongle immediately died on BOTH of them, the day of purchase. they were not recognized on any computer. great mouse if it worked but i can’t recommend taking the chance with it.

Out of the box the wireless USB dongle didn't work. After contacting their terrible support it has been 2 months now of waiting to get a replacement and counting. This seems to be a common issue with these and Razer has no interest in fixing it.

nothing was wrong i loved the designed and if you use palm grip its good

It's not very good,,,,it doesn't work for me anymore,,,it came out bad

Gave this present as a gift, it’s definitely worth the price.

Feels better than super light with more satisfying clicks

Their hardware is great, software is the worst in the business. By a long shot. If you dont want to be constantly troubleshooting to no avail, look elsewhere.

terrible quality mouse. stutters and freezes which is absolutely unacceptable when you’re playing fps games.

I've been using the RAZER Viper V2 PRO ultra lightweight Esports mouse for the last three days. Overall, I think it's a fantastic wireless gaming mouse that went above and beyond my expectations for design and performance. When I unboxed it I was extremely surprised at how deceivingly lightweight and perfectly balanced it is. It seriously feels like the mouse is empty. Which is great because if I play competitively the last thing I want to feel is wrist fatigue. Additionally, The mouse charged very quickly and the battery life was excellent. After three days of heavy use it only lost 10 percent of its capacity. The wireless connection is flawless. I never noticed any lag stutter or erroneous double clicks. Also, I love that I can pre-set multiple DPI settings in the Synapse software. Furthermore I love that I can change the DPI level with a touch of a button. This is a seriously a great mouse and if you are a competitive gamer that needs an ultra light mouse you will love the Viper V2. I highly recommend it.

The battery died within a month, Razer requires you send in the defective mouse instead of replacing it.
