Over the years, Razer has been my go-to for most of my gaming and computer peripherals including their high-performance mice. With the release of Razer’s new Viper V3 Pro mouse, they continue to impress and one up themselves by somehow making it even lighter and faster. I’ll start by mentioning I have owned every generation of Razer’s Viper mouse line as well as other manufacturers and I always end up back with the Viper line mice for several reasons.
Unboxing the V3 Pro was about as simple and self-explanatory as you can get, especially if you’ve owned Razer Products in the past and don’t have to install any new software; basically, a simple plug-and-play peripheral. If you haven’t, I would suggest downloading the recommended Razer software that can be used to customize the Viper along with any other Razer peripherals. In the box includes the mouse, USB-C charger and dongle for the wireless connection, instructions and grip stickers for the mouse that you can either install or leave off depending on your preference. Once the mouse is fully charged, you are good to go on most computers that automatically sense new devices and install the appropriate drivers if necessary.
Although I’m sure I have become “groomed” and accustomed to the Vipers’ design and ergonomics over the years, in my opinion it just feels more comfortable in comparison to the competition. After previously using other mice, I have noticed my hand will sometimes cramp up over time. With the new Viper V3 Pro, the design and aesthetics are identical to their last V2 model until you look “under the hood”. Being that both models are extremely light, the V3 weighs only 54 grams, you probably won’t notice a difference in the weight. However, once you flip it over to check out the underbelly and begin to use it, you’ll notice how much more “buttery” smooth it feels because of the larger slip pads on the bottom which cover more surface area and make it easier to maneuver. Utilizing the included Razer HyperPolling wireless dongle, which has a true 8000 Hz wireless polling rate, coupled with their Gen-3 optical mouse switches and the Gen-2 Razer Focus Pro optical sensor, which has smart tracking, motion sync and asymmetric cut-off, the gaming competition won’t know what hit them with such precise movement and lightning-fast responses. The other benefit that I almost always forget about, only because I rarely have to do it, is the rechargeable battery lasts nearly 100 hours on a single charge meaning less down time.
As I mentioned previously, the Razer Viper family has always been my favorite mouse and the new V3 Pro did not disappoint. I would highly recommend the new Viper V3 Pro, as well as many other Razer products, to anyone in the market for the latest and greatest peripherals and want a leg up on the competition or even as an everyday mouse.

Packaged in classic Razer packaging, you will find your mouse, the dongle and a very generously lengthed USB-C to USB-A cable.

I love the external design of the dongle that also has a USB-C port and connects to the same cable as your mouse. As a result, you can run the braided USB cable to your desk to place the dongle as close to your mouse as possible. When the mouse needs charging, you just disconnect the cable from the dongle and connect it directly to your mouse to charge.

Upon first use, the sensitivity was too much and it was all over the place and I couldn't adjust it to my liking. Looking online, there was a firmware update for both the dongle and the mouse and once applied it worked smooth as silk.

I go through a lot of gaming mice but I settled down on a Razer Deathadder V3 wired mouse about a year ago as I really liked the feel and responsiveness to it for playing games. I've been using it for about a year so I was delighted to see the Viper V3 Pro has the same basic design but is just a touch smaller. In comparison, it has better clicks and moves better because there is no cable getting in the way. Pictured side by side, you can see they are very much related.

I play Fallout 76 and World of Warcraft daily so I was able to get right in and judge the feel and responsiveness of the Viper V3 Pro compared to not only my Deathadder V3 but my Corsair M75 Wireless and the Viper V3 Pro is the superior mouse no question. It handles much better and passed my flick test with top marks. Moving and aiming is very responsive and for the first time it is on par with wired mice if not superior to most except the best. My only problem now is I'm so used to tugging the mouse from time to time to adjust for the cable on my previous wired mice that I find myself phantom tugging on the Viper but i'm sure this will subside sooner than later.

I do not like over complicated mice with all types of buttons and gimmicks and the straight forward functionality of the Viper with just two additional buttons on the side is perfect. It is spartan in the best way.

There are also quality of life improvements too and two things I love: One is the Viper doesn't have a slot for the dongle which I appreciate as I prefer the solid ergonomics of the Viper as is. Second is the indicator light on top that lights up when charging or first waking up the mouse to let you know it's ready to go then quietly fades away. The M75 and several other wireless devices I've tried either don't have an indicator light or it stays on the entire time in use which is distracting. These little design decisions go a long way.

I consider the Viper V3 Pro the big BIG brother to the Deathadder V3 and it is now my new daily driver.

Fantastic!

Razer Viper V3 Pro Ultra-Lightweight Wireless Optical Gaming Mouse

I’ve used my Razer Viper for 9 days now, and the battery is at 24%. I have another wireless gaming mouse of a different brand, but it taps out after about 3-4 days. Of course, any mouse I use is for gaming and general office work. I game quite a bit, but I do other things and office work with it as well, so I’m not sure how the battery charge would hold up if you were gaming all day every day. Regardless, plug it in overnight and you’re good for another week or two depending on your use.

I used the Wi-Fi dongle that came with it (don’t know if it works with BT or not although I don’t think it does, but for me I have a love/hate/hate relationship with Blue Tooth so, personally, I prefer not to use BT if I have a choice), and it’s worked flawlessly. If you prefer, you can use it wired as well.

If you look at the specs you’ll find this: Razer Viper V3 Pro Wireless Esports Gaming Mouse: Symmetrical - 54g Lightweight - 8K Polling - 35K DPI Optical Sensor - Gen3 Optical Switches - 8 Programmable Controls- 95 Hr Battery. Overall, this means that this mouse has very good hardware and should perform at professional esport levels for a long time. As far as 8K polling goes, that just means the mouse reports its movements/clicks etc. 8000 times per second to your computer, if you want it set that way. Standard polling is 1000 times per second. The higher the polling the lower latency your mouse will have; however, latency decreases a little less with each bump up in polling. Also, high polling rates degrade battery charge more quickly. High polling rates, while some gaming situations may call for the slightest edge it may give to the player, are hard to notice in ordinary gaming or regular use of the mouse.

In my personal use I’ve found that the Razer Viper is lightweight yet not to the point where a breeze will move it where you don’t want it to go – if you’ve used a “gaming” mouse before, you know there’s a line where if it is too light it will bring problems with it. I find the Viper to be just the right weight, yet it moves smoothly and easily on whatever surface you prefer. By the way, I’m an adult male with an average size hand but with longer fingers and this mouse is long enough to fit my hand and reach properly. It doesn’t set high at the top where your palm rests but more in the mid-range so that if you slide a keyboard tray back under your desktop and your mouse is on the tray, it clears the underside of the desktop just fine.

My other gaming mouse (mentioned above) for some reason (no matter how I adjusted the response time when clicking the mouse) would often interpret a fast double-click as a single click – really annoying for anything – gaming or general office work. The Viper has operated flawlessly in this and all other regards. I have it set at the default setting for click sensitivity.

I use the extra buttons on the left side of the mouse in place of some of the sometimes awkward required keyboard combination keys to execute certain moves in a game. I have a problem with my left pinky finger reaching the left control key so the number 4 button on the left side of the mouse handles this with ease. Same way for the 5th button. While the Viper allows you to use all other buttons in secondary ways (through its Razer Synapse 3 software for your computer) so that you can have controls as if you had a 10-button mouse, I don’t use this feature, but you might depending upon your gaming experience.

Overall, this is an excellent gaming mouse with many rave reviews elsewhere. I really like it for the use I put it to and I think you will too!

I'm not going to lie, when the delivery guy handed me the package, I thought it was empty. Opening it and seeing the box inside and picking it up, it still felt empty. That is how obnoxiously light this mouse is. Getting it out, and ready to use, and even now after using it in a variety of games, and general browsing, I can't quite get used to how little this thing weighs. But I am coming off of using Razer's Naga Pro for the last 4 years, this makes that feel like a brick.

Now, all that out of the way, I'm not sure the exact market for these Ultralight Mice. I am guessing for better snap reaction speed in twitch reaction style FPS games. Less weight, so less carried momentum when moving the mouse quickly, so less compensation needed to correct potential over movements or something, I'm having the opposite problem, the mouse is so light I am moving too much now lol. Though while I this mouse and the whole Ultralight category might not be meant for me, I do appreciate that people have a preference for this kind of thing. So I have to give credit.

The Viper V3 Pro is responsive, the wireless performance is great, and the battery life is way higher than necessary, but since there's no charging cradle compatibility here, I can see why they went out of their way to make the battery life as long as they could within the confines of the weight. The included USB A to C cable is braded and flexible as to not interfere when using it and charging at the same time. Overall, I don't have any complaints with its build as intended. But while using it I miss a lot of the creature comforts my other mice provide.

The scroll wheel lacks a left and right tilt, something I am used to and make heavy use of, and the DPI switch being on the bottom of the mouse makes it so you can't change DPI on the fly. The large skates on the bottom of the mouse do not glide on my mouse mat as well as I would like, and I value that above a lighter mouse a whole lot.

I think this mouse ticks all the boxes for a good ultralight mouse, and if that's what you are after, I'm sure you will get a lot of mileage out of this one. For me however, it misses the mark by sacrificing functionality I have grown accustomed to over the years with other mice.
