Customer Ratings & Reviews

Let's talk about a gaming mouse that seems determined to pack just about every premium feature imaginable into a single package: the Razer Basilisk V4 Pro. Razer has always had a reputation for making high-performance gaming peripherals, and the Basilisk V4 Pro takes that philosophy to another level. Right out of the gate, we're looking at a sleek, aggressive design that manages to balance a traditional gaming aesthetic with genuinely useful ergonomics. Between the sculpted right-handed shape, dedicated thumb rest, textured side grips, and customizable RGB lighting, this mouse definitely looks and feels like a premium piece of gaming hardware. But the real story is what Razer has managed to squeeze underneath that exterior. At the heart of the Basilisk V4 Pro is Razer's latest Focus Pro 50K Gen-3 optical sensor, supporting an absolutely ridiculous 50,000 DPI, 930 IPS tracking speed, and up to 8,000 Hz polling. Now, let's be realistic: practically nobody needs 50,000 DPI for everyday gaming, and cranking the sensitivity that high certainly isn't going to magically make you a better player. What actually matters is tracking accuracy, consistency, and responsiveness. This is where the sensor shines, delivering the kind of precision that competitive gamers demand without sacrificing the versatility needed for other genres. For competitive titles like Counter-Strike 2, where accurate flick shots, controlled recoil, and tiny crosshair adjustments can determine whether you win or lose an engagement, having a responsive and consistent mouse is incredibly important. The 8,000 Hz polling capability is impressive on paper, although the real-world improvement over a properly configured 1,000 Hz mouse will be relatively subtle for most gamers. Still, knowing the hardware has that additional performance headroom is certainly a nice bonus. Pair that with Razer's fourth-generation optical switches, rated for 100 million clicks, and you have a serious piece of hardware designed for fast, reliable inputs. Where the Basilisk really separates itself from traditional competitive gaming mice is versatility. Rather than chasing the absolute lightest possible design, Razer has included 14 customizable controls, including additional thumb buttons and its signature multifunction trigger. This makes it especially appealing for games where having abilities, equipment, or shortcuts immediately accessible can make a noticeable difference. Whether you're swapping equipment in an FPS, managing abilities in an RPG, or assigning frequently used commands, there is an impressive amount of flexibility available through Razer Synapse. And I can't overlook the scroll wheel, because it's arguably one of the most useful features on the entire mouse. The second-generation HyperScroll Tilt Wheel offers traditional tactile scrolling, a finer 48-step precision mode, and an incredibly convenient free-spin option. Being able to switch between carefully controlled scrolling and quickly flying through lengthy documents, menus, or webpages is one of those features that might sound unnecessary until you get accustomed to having it. The automatic switching functionality adds another layer of convenience, although the free-spin mode may feel a little too sensitive depending on personal preference. Battery life is another area where Razer deserves credit. The Basilisk V4 Pro is rated for up to 200 hours using HyperSpeed Wireless at 1,000 Hz, which is excellent for a feature-packed wireless gaming mouse. That figure drops to approximately 54 hours when running at the maximum 8,000 Hz polling rate, so there is definitely a trade-off between performance settings and battery endurance. Personally, I think 1,000 Hz is more than sufficient for the vast majority of gaming sessions, making the additional battery life the more practical option. The mouse also supports Bluetooth and wired connectivity, making it useful beyond a dedicated gaming PC. Naturally, Razer hasn't forgotten about RGB. The seven-zone Chroma lighting, including the illuminated scroll wheel, logo, and underside lighting, gives the Basilisk a fantastic appearance on a gaming desk. It isn't quite as elaborate as the lighting configuration on some previous Basilisk models, but it still looks sharp without becoming overly distracting. Through Synapse, you can customize the lighting, button assignments, DPI stages, and individual profiles to suit different games and everyday applications. Of course, there are a few drawbacks worth mentioning, and the biggest one is the weight. At approximately 100 grams, the Basilisk V4 Pro is noticeably lighter than its predecessor, but it's still considerably heavier than modern ultralight competitive mice. As someone who appreciates the lightweight design and ergonomics of the DeathAdder V4 Pro, this is one trade-off that stands out to me. Both mice are ergonomic, but they take noticeably different approaches. The DeathAdder features a more streamlined shape designed around quick, effortless movements, while the Basilisk offers a wider, more sculpted body with a dedicated thumb rest and additional controls. That extra weight and bulk might not appeal to everyone, especially gamers who spend hours playing competitive shooters like Counter-Strike 2. However, for those who prioritize additional functionality and a more substantial grip, the Basilisk's design certainly has its advantages. Ultimately, it comes down to personal preference rather than one ergonomic design being universally better than the other. I'm also not completely sold on every additional button. While customization is always appreciated, the new AI shortcut feels more like an unnecessary addition than something gamers were actually asking for. Its positioning alongside the traditional thumb buttons can also make reaching certain controls feel less natural. Thankfully, the function can be reassigned through Synapse. And speaking of software, although Synapse offers tremendous customization, having to rely on another background application to access some of these features isn't necessarily everyone's favorite thing. Then there's the price. This is undeniably an expensive gaming mouse, especially considering the wireless charging dock isn't included and must be purchased separately. For a product positioned this far into the premium category, I would have liked to see Razer include the dock rather than treating it as another optional accessory. It's a disappointing omission that makes an already pricey mouse even more expensive if you want the complete wireless charging experience. It also makes upgrading from an already excellent Basilisk V3 Pro harder to justify unless the newer features are particularly appealing. All in all, the Razer Basilisk V4 Pro is an outstanding all-around gaming mouse that successfully blends competitive-grade precision with everyday comfort, customization, and versatility. It may not be the lightest mouse on the market, and some of the added features feel unnecessary, but the excellent sensor, sophisticated scroll wheel, responsive optical switches, and impressive battery life make it a compelling package. If you want a premium wireless mouse capable of handling everything from competitive shooters to immersive single-player adventures and everyday productivity, the Basilisk V4 Pro absolutely deserves consideration. Just be prepared to pay a premium for all that technology.

So this is the v4 Pro version of Razer's Basilisk line of gaming mice. The White is striking and looks incredible right out of the box, especially with the panel separations kind of giving it that mechanical, robot/gundam/spaceship vibe. Absolutely looks amazing, and even better if the rest of your setup is in white. I love the little underglow lighting it has on the back end. Performance wise it's what we've come to expect from razer overall, great button feel, responsive sensor, plenty of customization. So if you've used Razer gaming mice in the past, you know what your getting here. And of course as the cherry on top we also have compatibility with the charging puck for using their fancy mousepad charging system. The wireless dongle included can store under the charging puck space as well so no worries of losing your dongle, and razer supports multiple devices on a single dongle for a lot of these newer products so with a little setup you can get your wireless accessories running from a single usb port, for less dongles less usb ports being taken up by your basic peripherals etc. The Basilisk line is the ergonomic mouse line, and for me its shape is comfortable and fits in my hand really well. But there is no adjustability here so if you have a larger or smaller hand I can't promise it will be as comfortable for you as it is for me. One of the new features advertised here is the "perfect 180" It's not set by default thankfully, but its something you can setup now and map to a button to give you a one click perfect turn around in whatever game you have it set to. This goes a little beyond what I would expect most people would be considering as fair play. Some games have something like this as a movement option already and for those games sure, fair play everyone has access to single button turn around, but this can be calibrated and setup for basically any game, and I feel like that is just cheating. So, if you're in a pro circuit or league or whatever check with their rulings on things before you go ham with it. The dedicated AI button is kind of a miss for me, but it can be remapped to whatever I want so that's whatever. Overall, I think the Basilisk has been my top mouse choice for a while now, with the Naga being a close second. It's light weight enough to be easy to swing around the mousepad without being completely into the ultralight class where you start going into barebones functionality for the sake of weight reduction. It's a nice middle ground where you can have fancy features but it's not a brick.

I’m a huge Razer fan, especially when it comes to their mice. I was using the Basilisk Pro V3, same white color as this new one. I love it! The only reason for upgrading was the better battery life, which was not bad, but I wanted to recharge it less. Also, there were some other perks moving to this newer version. On top of it, the new Modern Warfare 4 game just came out and I figured after 2 years, it might be worth seeing what’s improved out there. Side by side, these 2 mice are nearly identical in color and lighting. There are 2 extra buttons on the V4, which are discreetly added in a way to make the mouse not look too weird. The click sound on the V4 is probably about twice as loud as the V3 for some reason. My first time using it, it sounded ultra loud while playing my games, but I’ve gotten used to it since. I use these mice in 2.4GHz mode so I don’t ever have to deal with pairing or a cable, and the V3 worked flawlessly. I have had a couple of issues where the V4 seemed to go to sleep and would not wake up unless I manually turned the mouse off and back on, which is a bit annoying. I even checked the settings and nothing seemed out of the ordinary, just a standard sleep time. I imagine this is an easy software fix. Customization is nice, as with any Razer mouse with the Synapse software. I love how my profiles carry between computers and can be cloud synced—one of my favorite parts about Razer mice. Adding a new mouse is simple as plug and play, and I can jump right into the games all the same. Some custom button programs do have to be re-assigned though, which is unfortunate, but I’m still happy with it. The precision tactile scroll is…interesting. Part of me likes it, while part of me isn’t sure if it’s necessary. I disable the free scroll in settings and have been switching between the standard tactile scroll and this new one, still seeing which one fits me best. Overall, this mouse has been a nice step up for me, definitely in the battery department. Been about 6 days using this mouse, and I am on my computer probably around 10+ hours per day, while still having a 63% charge on it. I do like how the upgrade from V3 to V4 was not a huge design change, as I’ve been happy with the weight and design of this mouse. You can see my picture of the 2 mice in a side-by-side comparison below. Included is the USB-A dongle (adapter), a USB mount that connects USB-A & C, and a black cable. Not sure why a white cable wasn’t included to match the mouse like the V3, but the accessories make compatibility easy.

I tried this mouse with several games and the mouse performed extremely well. The specifications are top rate. A couple features that impressed me right away were the physical design of the mouse and the design of the dongle such that it can be connected via an included ‘dongle docking plug’. What this design point provides is the ability to quickly move from a wireless connection to a wired connection. Relative to the physical design of the mouse, the tactile surface on each side of the mouse allows you to grip the mouse with a light but non-slip hold. The concave shape of the left and right buttons was very instrumental in keeping your fingers in an optimal position – just wonderful. These design points are important because they help you to not cramp your hand and at the same time permit you to make quick movements smoothly and confidently. Lift distance like all the specs including the 8000 Hz polling were all top-notch. The tilt wheel felt precise and sure-fire. A giant tip of my cap to the engineers who designed this beauty. I loved the 200 hours of battery life, the provision of 14 customizable controls and inclusion of 3 side buttons. I would highly recommend this mouse with its superior specifications and its wonderful physical design that hugs your hand.
