The previous adage is that you simply shouldn’t repair what isn’t damaged, and that’s just about the strategy Razer has taken with the Basilisk V4 Professional’s basic form and really feel. As somebody who makes use of the usual wired Basilisk V3 each day and loves it, I’m fairly pleased about that, and it’s very becoming for a product that actually has the phrases ‘model 4’ in its identify. The awkward half is that my previous mouse already felt correct, responsive and cozy. The V4 Professional is a implausible mouse in its personal proper, however at £169.99 it has to supply a good bit to make changing an current Basilisk worthwhile.
The left facet nonetheless sports activities that fancy wing in your thumb to relaxation on its mighty laurels, and the angular entrance and rounded physique stay acquainted. There are small modifications: the primary click on panels now not wrap down the edges barely, and some angles and joins are totally different. Relying in your grip, these may matter, however with my regular palm grip it feels largely an identical to the earlier Basilisk. It was comfy earlier than, and it’s comfy now.
Razer has squeezed some further controls onto this little beast, bringing the marketed complete to 14. That’s programmable controls, together with scrolling and tilting the wheel, relatively than 14 separate buttons scattered across the shell. The 2 horizontal facet buttons have turn into three, with the separate multi-function set off giving your thumb 4 controls in complete. The rear two stay straightforward to make use of for ahead and again when searching, and I can attain the third with the tip of my thumb after a small grip adjustment. The fourth sits farther ahead, although, and doesn’t fall naturally inside attain of my small fingers. Razer describes its place as extra accessible, however my petite fingers name it doing yoga.
The V4 Professional Comes In Black Or White
The buttons themselves really feel nice. The primary optical switches have a satisfying click on, with the left and proper sounding pleasingly constant. The facet controls really feel good too, and I haven’t had any unintended presses, which is at all times a very good signal. Construct high quality feels very like my V3 which has survived a number of years of abuse, so I don’t have any actual issues about it giving up and collapsing right into a heap of high-priced plastic.
The rubber coating on each side additionally feels acquainted, which worries me extra. My V3’s grips wore down shortly. I can’t predict the V4’s sturdiness after solely a short while with it, however I’d have appreciated a extra reassuring change there. For a palm-gripper like myself, the grips carrying down isn’t that little bit of an issue, however a claw-grip consumer may discover it extra annoying.
At roughly 100g, this isn’t an ultra-light mouse, and I’m proud of that. I perceive the attraction of lighter fashions, particularly for giant actions at low sensitivity, however I like having a bit of weight in my hand. Razer’s marketed 12g saving is towards the wi-fi V3 Professional 35K, which weighs 112g. My wired V3 is round 101g excluding its cable, so getting wi-fi operation into a lot the identical weight is the extra related change for me. All that stated, when you undergo from wrist pressure, a lighter mouse generally is a good udea.
Beneath, a detachable plastic puck covers the dongle compartment and will be changed with the suitable wireless-charging puck. The compartment holds the tiny USB-C dongle with out the USB-A adapter that additionally comes within the field. I’d want room for the adapter too, nevertheless it’s a small criticism.

If 14 programmable buttons aren’t sufficient and you want extra assignments, the Hypershift clutch offers you a second layer when you maintain it down, reverting once you launch it. You possibly can assign one other mouse button to do the identical job, too, in fact, and might simply take away the Hypershift mapping totally when you like. I’ve by no means needed that many instructions mapped to my mouse, nevertheless it’s a helpful method to increase your choices with out including extra bodily buttons.
The scroll wheel affords probably the most instantly pleasurable enhancements. Alongside the acquainted tactile and free-spin modes, Precision Tactile doubles the steps round a whole rotation from 24 to 48. The notches are nearer collectively, supplying you with extra particular person clicks for a similar motion. It feels wonderful. Free-spin stays implausible for getting by way of lengthy webpages and paperwork shortly, too. And likewise simply to take a seat and spin prefer it’s a bloody fidget toy.
I’m nonetheless much less eager on Sensible-Reel, which switches between tactile and free-spin mechanically in keeping with scroll velocity. You possibly can regulate its responsiveness in Synapse, however generally it switches once I didn’t need it to. I like sending a web page flying once I select to; having the wheel make that call is much less interesting. Fortunately, it’s non-compulsory. As a substitute, you possibly can simply have one of many buttons mapped to change between tactile and free-spin at will.

Razer has at all times been very… er, keen about making use of RGB to the whole lot, which makes the revised lighting a curious step backwards to me. My wired V3 has 11 zones, with a skinny strip across the decrease edge creating its underglow, principally making it seem like the type of automotive teenage me at all times made in Want For Pace: Underground. The V4 Professional drops to seven zones, largely concentrated in a thicker rear lightbar that’s virtually totally coated by my palm grip. With that coated and the Razer emblem hidden beneath my palm as nicely, the one seen RGB is on the scroll wheel. You may want the subtler impact when you don’t take pleasure in having a disco in your hand, however I miss the previous association. Sure, I do know, RGB and gaming has a protracted and sordid historical past, however I type of like having a private gentle show, okay?
Connectivity is beneficiant: USB-C wired play, the included HyperSpeed Wi-fi Gen 2 receiver, and Bluetooth pairing for as much as three units, chosen utilizing the underside connectivity button. Counting wired operation makes this Razer’s five-way connectivity. The wi-fi connection has been flawless in my use, with no noticeable points, and I actually couldn’t inform from utilizing it that the mouse wasn’t wired. Coming from my wired V3, that’s an enormous praise. And it wasn’t just like the HyperSpeed Gen 2 was given a straightforward activity: I’ve a number of different wi-fi units working on the identical pc and a bunch of different indicators flying across the place, so there was loads of possibilities for interference. Regardless of that, it by no means as soon as misplaced connection, lagged and even coughed gently. Good job.
Many of the different modifications are below the hood. The Focus Professional 50K Optical Sensor Gen 3 helps as much as 50,000 DPI, with Razer ranking its monitoring velocity at 930 inches per second and acceleration at 90G. DPI describes motion counts for a given distance; the opposite figures describe how shortly you possibly can transfer and speed up the mouse whereas it maintains monitoring. My authentic V3 tops out at 26,000 DPI, 650 IPS and 50G, for comparability. The later V3 35K revisions use a 35,000-DPI sensor, so the dimensions of the specification leap will depend on which Basilisk you’re evaluating. Whichever one you compre towards, it’s a reasonably good efficiency leap.
The Professional helps as much as 8,000Hz polling wired and wirelessly out of the field. That’s the interval between stories, relatively than the whole time between transferring the mouse and seeing the outcome on display. Body Sync coordinates sensor scanning with these stories so the motion knowledge is captured nearer to when it’s despatched to your PC, which Razer says reduces movement latency and improves battery effectivity.

These are sizeable will increase on the specification sheet, however the regulation of diminishing returns is firmly at work. I’d be mendacity if I stated I observed drastically improved precision or velocity over my V3, which already saved up and felt correct. A better most DPI isn’t mechanically better accuracy, both, and I wrestle to think about needing something near 50,000. Maybe an ultra-competitive Counter-Strike god whose profession will depend on tiny variations in enter response would get extra out of all of the enhancements. I’m simply right here attempting to faux I’ve the identical shooter reflexes I had once I was a young person enjoying CoD. I don’t. In consequence, I can’t actually let you know this mouse feels higher on a technical stage, though it basically is best on paper.
Battery life has met my expectations, though I haven’t accomplished a timed rundown take a look at. Razer claims as much as 200 hours on HyperSpeed and 275 hours on Bluetooth, however the first determine is at 1,000Hz, relatively than the total 8,000Hz. You shouldn’t learn the longest runtime and highest polling fee as simultaneous advantages. Personally, I’d fortunately prioritise battery life over most polling. Synapse additionally affords computerized polling-rate switching when an software enters full-screen mode, which is separate from Body Sync. I often stick at 4,000Hz polling, in a bid to discover a stability between battery life and uncooked efficiency. I really feel like 200 hours is a beneficiant declare, however battery life was nonetheless greater than adequate.
Synapse itself is usually high quality. Remapping buttons is easy, and the macro editor affords a very good vary of instruments for recording or manually constructing sequences. I haven’t had any points with the macros I’ve tried, they usually can be utilized with out Synapse. Linked Video games can mechanically choose a profile when a sport launches, too, though it missed loads of my put in video games; you possibly can scan once more or add them manually.
Mouse Rotation is one other helpful possibility. It compensates for the angle at which you maintain the mouse by adjusting how sensor motion is interpreted. I set a four-degree offset and intentionally angled the mouse: motion that might in any other case drift sideways stayed straight. Straightening the mouse once more produced the alternative impact, making the adjustment straightforward to see. I usually maintain mine pretty straight, so I don’t want a lot correction, nevertheless it works.

Guide profile switching has moved from the V3’s devoted underside button to the programmable M1 edge button beside the left click on. If you’d like that operate, it occupies a management you could possibly in any other case assign to one thing else. The onboard reminiscence has 4 assignable slots plus a hybrid slot in your last-used software program profile, and making a profile in Synapse isn’t the identical as saving it to a kind of slots. As soon as mine have been assigned correctly, switching and DPI modifications labored with Synapse closed, and empty slots have been skipped. My examined macros labored after exiting it too. With the ability to configure the mouse after which largely use it with Synapse uninstalled is a particular constructive for me.
The lighting limitation nonetheless annoys me. I assigned matching static colors to my take a look at profiles so I might determine them at a look, however with Synapse closed the mouse continued spectrum biking. Razer says lighting results aren’t saved onboard, a distinction the software program doesn’t make particularly clear. Wanting purple for one profile and blue for an additional isn’t an unreasonable demand, and it shouldn’t want a background software simply to recollect my selection.
Razer additionally affords browser configuration by way of Synapse Net, however the V4 Professional isn’t at the moment listed amongst its supported units. That’s a bummer, as a result of dealing with setup in a browser would spare folks downloading the entire desktop package deal. It’s not that Synapse is especially unhealthy, however individuals are rightfully aggravated at requiring one million totally different apps to be put in for the whole lot nowadays, and Synapse is yet one more factor absorbing system assets.
However the excellent news is the overwhelming majority of options don’t require Synapse, so you possibly can obtain it, get some profiles arrange, fiddle a bit of after which delete the software program totally.
Good 180 is a kind of that requires Synapse working, although, and is designed to show your character round with a button press, configured in your sport settings. It isn’t one thing I want, and Razer warned in the course of the briefing that automated actions like this will breach aggressive video games’ guidelines.

Then there’s AI Immediate Grasp function. It affords primary templates that wrap your textual content in quite simple directions earlier than putting the assembled immediate into an AI chat window; in my setup, the service was ChatGPT. The ‘Rephrase’ possibility imported highlighted textual content mechanically once I hit the button, however Summarize didn’t throughout my makes an attempt, eradicating a lot of the comfort from an apparent use. Somebody repeatedly performing the identical activity may save a couple of steps, I assume. I struggled to see why I’d use this as an alternative of opening ChatGPT myself.
The AI Immediate Grasp picture function was much more hilarious. Open it, write up your textual content and hit the ship button, and all it does is add ‘Create a picture of’ to the start of your textual content after which ends your textual content with ‘in X model.’ Then left me to press ship in ChatGPT. Very useful, Razer. Not.
Calling this Immediate Grasp feels formidable. I’ve remapped the AI button to a screenshot shortcut as an alternative, which has been exceptionally helpful when reviewing video games as a result of now I don’t should paw at my keyboard like a confused Spaniel. That’s an additional management incomes its place on my mouse.
Let’s discuss equipment, we could? The non-compulsory new Mouse Dock V2 Professional combines magnetic charging with an built-in 8,000Hz receiver and the appropriate charging puck. It could pair a appropriate keyboard alongside the mouse to liberate a USB slot, however the Professional’s included receiver already affords that sharing and the 8K polling. I haven’t examined the dock; at £69.99 individually, I believe it’s overpriced for what is basically a glorified wi-fi charger. The present mouse bundle provides it for £40, which is less complicated to contemplate. It’s a vibrant parking area with a Razer tax connected, and but annoyingly I’m nonetheless tempted.

The cheaper Basilisk V4 HyperSpeed prices £109.99. I haven’t examined it, however Razer’s specs present the primary variations beneath. Sure, HyperSpeed can also be the wi-fi expertise’s identify, together with on the Professional. Thanks you for making issues further complicated. I’ve sufficient issues remembering the names of issues with out your assist, Razer.
| Important distinction | Basilisk V4 Professional | Basilisk V4 HyperSpeed |
|---|---|---|
| Worth | £169.99 | £109.99 |
| Physique and weight | Proper-handed, thumb relaxation; approx. 100g | Identical listed dimensions and broad form; approx. 94g |
| Sensor | Focus Professional 50K Gen 3; as much as 50,000 DPI | Focus X 33K Gen 3; as much as 33,000 DPI |
| Wi-fi polling | As much as 8,000Hz with included receiver | 1,000Hz included; as much as 8,000Hz with a appropriate HyperPolling dongle or Mouse Dock V2 Professional, bought individually |
| Controls | 14 | 12 |
| Scroll wheel | Consists of Precision Tactile | No Precision Tactile |
| Bluetooth pairings | As much as three units | One machine |
| Claimed battery life | As much as 200h wi-fi at 1,000Hz; 275h Bluetooth | As much as 140h wi-fi at 1,000Hz; 225h Bluetooth |
The Professional’s finer scrolling, further controls and Bluetooth pairings are helpful variations, however the cheaper mannequin’s decrease sensor ceiling wouldn’t fear me primarily based on how nicely my older V3 performs. For my wants, the HyperSpeed could be the extra tempting buy.
In Conclusion…
Taken by itself, the Basilisk V4 Professional is a implausible mouse, albeit type of costly. The acquainted consolation, wonderful wi-fi connection and improved wheel have made it a pleasure to make use of, and the software program annoyances haven’t stopped it from doing its important job nicely. As a revision, it makes smart enhancements to a design I already appreciated, and packs some fairly massive efficiency upgrades below the attractive plastic shell, too.
I nonetheless wouldn’t suggest spending £170 changing a Basilisk V3 mannequin, although. For my on a regular basis work and gaming, the modifications don’t add as much as a leap I’d pay that a lot for, and I wouldn’t let you know to, both. I’d preserve the mouse I’ve, or have a look at the cheaper HyperSpeed variant if I needed wi-fi. Somebody shopping for a brand new mouse particularly for the Professional’s further options has a stronger cause to contemplate it, however upgrading from a wonderfully good Basilisk is a more durable promote.
