Razer - Viper V4 Pro Ultra Lightweight Optical Gaming Mouse with 180 Hour Battery Life - 8k Polling Rate - Wireless - Black

The mouse is fantastic. It feels good in the hand, extremely light, buttons are very snappy, movement is extremely responsive, software is good. I honestly had a really good mouse already, but it was a little older and about 100 grams. With this mouse being half the weight I thought I’d treat myself and I’m glad I did. This thing is just great, 180 hr battery at 1000 Hz, but I really like the dynamic sensitivity. My previous mouse didn’t have that and I didn’t know what I was missing. Overall I was skeptical because of the price but I’m glad I bit the bullet and bought it

To start off, I have a ton of experience with gaming mice and have used every notable hardware design dating back to around 2003. Back when the only optical sensor competition was pretty much ST and Agilent designs. I even tested prototypes from a few notable companies around 15 years back, so you can say.. I've been around. What particularly interested me about this mouse is the fact that it has a truly next gen hardware.180hr battery life @ 1000hz? Yeah, that's no joke considering this mouse is using relatively newer Airoha wireless RF with a dedicated power management chip. Sensor also has a newer DIP package design, which I assume means it's a bit revised under the hood as well. There's no public information on this but they likely modified array size to be more competitive with another brand in certain aspects. I really like this mouse. It's lightweight, and the shape is quite neutral for me. Build quality is overall great considering the 50g weight, though I don't exactly have issues with mice being too heavy as long as the overall design makes sense per how I actually grip the thing. I used to use mice in the 100g area just fine, but this is subjective and everyone is different. The scroll wheel itself is very impressive. Feels like a mechanical design, but somehow optical. I don't know how long this will last in terms of the notches and tension wearing down (like a true mechanical design), but initial impressions are great. Main clicks are also okay.. I've used inductive switches from a competitor product and everything else on market feels like an innate downgrade on this front, but I can see some people preferring these just in the sense that they're static mechanical optical switches. So, if I had to fault anything, it would be this subjectively. Software is great. Web Synapse works as expected and lets you pretty much do everything without the need of downloading the actual razer synapse software. I actually have mine installed because I use both Razer desktop speakers and their Xbox controller, so it's not something that needed per say, but I can see people really enjoying the web based aspect quite a bit, especially competitive gamers. The sensor feel is extremely responsive It might be "frame Sync" but this is the only mouse on the market that feels exceptionally nice on 360hz+ monitors for me (I use 500hz). I'm sure it's a combination of the Airoha microcontroller and revised sensor design too, but Razer pretty much nailed it here. As I implied earlier, this is truly a "next gen" mouse I can't really go super technical, but I will say that this mouse "feels" different than it's main competition.. in a good way. Polling is also hyper responsive as expected. More stable than legacy 1k mice from a decade ago. OVERALL: Is it worth the price tag? I'd say yes, but with a caveat. This is one of the few mice on current market that isn't reusing legacy hardware. You get both a newer RF wireless setup and revised sensor design on a physical level. Controller is also exceptionally stable at its 1000hz setting. The only thing I would ding at is that the main competitor to Razer has inductive switches now and I generally prefer those. I think they are the future for m1/m2 clicking. The caveat? You can get a mouse competitive to this one in regards to "sensor performance" for around $50 new these days.. but it will lack the 180hr battery spec and potential advantages of what I assume is frame sync. This is a 4.5/5 for me.. 5/5 if it had inductive clicks.. which I am biased to :)

So right off the bat, when I opened this box and grabbed the mouse, I noticed just how light it is. I knew it was supposed to be light, but it still shocked me. I love that it is light weight but not cheap feeling. It has a premium feel and look that you would expect in this price range. At first glance you might think this is overpriced for what may look like a basic mouse, but under the hood they applied a lot of upgrades and specs that really up the value of this mouse and earn it’s pro name. I won’t bother listing all the specs and details, others have already and the spec sheet shows them all, but what I will say is those specs make this a really reliable and capable mouse for extreme gaming competition. I do not compete in high stakes or even “pro” level gaming since, frankly, I suck too much. But I do enough gaming to notice when a piece of hardware is not performing well enough. That would be my old mouse. The wheel was giving out and the response was lacking. Enough that I could legitimately blame the mouse for missed shots. So a replacement was needed. My old mouse had a mechanical wheel that gave out too soon so I like that this wheel is optical but FEELS mechanical still. The wheel click is a bit stiff, good to avoid accidents, but not great if you use it a lot. For me this hasn’t been an issue. The left and right main buttons are clean and crisp clicks that feel instantaneous. I can’t blame them for a miss, (though I may still shout it out). There are two buttons on the thumb side which give you extra options for gaming and doubles as being helpful when navigating the PC as they become forward and backward buttons for webpages and file browser etc. These buttons are well placed to only be hit when you want to and not accidentally bumped during frantic playing. I also think it’s worth noting the DPI switch is on the bottom not somewhere up top. My previous mouse had it by the wheel and I can’t tell you how many times I accidentally hit that button and panic followed. The mouse also comes with a hyperspeed wireless Gen-2 Dongle and LED indicator which should sit nicely on most desk setups. The cable is long enough to reach my tower easily and the LED indicators are a great way to monitor the status of your device. By default they show connection status, battery life, and polling rate. Although these are customizable in the web app if you want to change them. It also comes with a nice little cheat sheet to show you what each color means for the default 3 settings. Speaking of battery life, this mouse claims a 180 hour battery life at 1k polling which is fantastic. I have not had a mouse with that kind of life in it so if that holds true, I will enjoy less frequent charging. And thanks to the dongle indicator, I will easily know when it is getting low. Also included in the box are some stickers, an information booklet and grip stickers if you choose to use those. I have found no need to though. I have relatively smaller hands than average, but the size of the mouse is great for my hands. My fingers rest comfortably and the body doesn’t feel too bulky like other, larger, button heavy mice have. I would call this more in line with average or “classic” mouse size. The bottom is smooth and glides nicely on multiple surfaces I tested it on and I had no issues with textures or contrast images on a mouse pad making the mouse jitter or jump. Overall, I think this is a fantastic upgrade to the pro model and no gamer; small or pro, will be disappointed with the performance. It may look simple and basic, but it is loaded with top end specs that will give you every advantage in the game you can get. Backed by a well known brand that continues to push the industry, you can’t go wrong with this mouse. I think the price is somewhat fair, though may be a bit on the high end. But if you don’t need all the features, you could get one of their lower tier models and know it’ll perform just as well.
