Razer Basilisk V3 Pro 35K review – a gaming mouse ideal for work and play

The Razer Basilisk V3 Pro 35K is a gaming mouse that attempts to do it all. It offers wired, wireless, and Bluetooth connections. It has a scroll wheel that can spin freely for super-quick scrolling or go clicky with the touch of a button – it can even tilt left and right too. A side button gets you an instant low-DPI sniper mode, and you can even add wireless charging as well.

For those up on their gaming mice, you might be thinking this sounds an awful lot like the Logitech G502 X Plus, and you’d be right. Both offer relaxed, ergonomic designs and loads of features, and both accept that they’re not the lightest options around. Instead, these two are vying to be the best gaming mouse for those seeking a single mouse that can turn its hand to just about any task, both gaming and productivity. Read on to find out whether Razer‘s version is the one to get.

Specs

Features

Where to begin with the features packed into the Basilisk V3 Pro 35K… Let’s go with the scroll wheel. It’s what Razer calls a Hyperscroll tilt wheel, which means it can offer both a conventional notched/ratcheted spin and a completely free flowing spin, as well as being able to tilt left and right.

The scroll style is altered via a button on the top, and new to this latest version of the mouse is that it can auto-switch between the two modes. In this auto-switch mode, called Smart-Reel, you can scroll slowly, and it offers a controlled, notched feel – ideal for switching weapons in a game, for instance – but a more vigorous spin will cause it to change to free-spinning until stopped by your finger or it runs out of momentum. You can also select whether the free-wheeling mode scrolls even faster.

These types of scroll wheels are super useful, not so much for gaming in my experience, but for general desktop work. I’m constantly switching between the two when reading web pages, navigating spreadsheets, or writing articles like this very review. Drop into free-spinning mode and you can cover vast distances with one flick. It’s also particularly useful in image and video editing apps, such as Photoshop. You can really quickly zoom in and out or pan around the screen.

The Smart-Reel function is a key advantage of the Razer over the Logitech G502 X Plus. Whereas the Razer uses an electronically-assisted method to switch scroll modes, the Logitech has just a mechanical switch. The action is the same – press the front-most top button on the mouse, just behind the scroll wheel – but the Razer requires just a light tap, whereas the Logitech needs quite a forceful, deep press, and it can’t offer the Smart-Reel feature.

As for the wheel tilt, this defaults to scrolling left and right, but the buttons can be programmed to anything you like. I’ve never particularly found these buttons to be very useful in my workflows, but they’re there if you want some extra functionality, and they can be great for activating the lean function in first-person shooters that support this feature.

Meanwhile, behind the scroll wheel button is a button that defaults to changing the mouse’s DPI setting. It can cycle between up to five different DPI settings, with Razer’s software popping up to indicate which setting you’re on. Sadly, the RGB lighting on the mouse doesn’t change to also indicate the setting.

Aside from the standard Back and Forward buttons on the side of the mouse, the only other extra button on the top side of the mouse is the “sniper” button on the side. This can be tapped by your thumb to momentarily drop the DPI to whatever setting you’ve programmed it to, or you can assign the button to another function.

Notably, where the Basilisk V3 Pro 35K falls behind the G502 X Plus is that the sniper button on the Logitech can be removed or its top spun round so that it sits further forward or back, to accommodate how you like to grip your mouse. What’s more, the Logitech has two extra buttons to the left of the main left button. It uses these to adjust DPI (by default), and I’ve always found them to be very convenient extra buttons.

On the underside of the Basilisk V3 Pro 35K is a profile button along with a slider for turning the mouse off or choosing between Bluetooth or 2.4GHz wireless modes. Towards the back, there’s also a round cover that you can remove to reveal a stowage space for the USB-A wireless dongle, and you can also replace this cover with a wireless charging puck that costs $20 and is compatible with Razer’s Mouse Dock Pro. However, the latter seems to be mostly unavailable at the time of writing.

Along with the mouse’s USB-A wireless dongle, it ships with a 1.9m (6ft) braided USB-A to USB-C cable and a USB-C to USB-A adapter. The cable can be plugged into the front of the mouse to charge and carry on gaming, or can be plugged into the adapter along with the wireless dongle to provide a convenient wireless connection close to your mouse.

Design

The design of the Razer Basilisk V3 Pro 35K is classic Razer, with it giving off a sleekness that most mice can’t match. It might not be to everyone’s liking overall, but there’s no denying the proportions and subtle details come together well. It certainly helps that Razer’s triangular logo looks good in any orientation.

The RGB lighting that’s integrated into the sides of the scroll wheel, under the Razer logo, and in a strip that runs around the base of the mouse is also subtle but fun. There’s a white version as well but oddly, Razer has chosen to keep the glossy black details of this black version in that model too, so you don’t get a purely gleaming white look.

Aesthetics aside, the Basilisk is a deceptively compact mouse. It has a flared-out section for resting your thumb and a slightly tilted-to-the-side ergonomic shape, rather than a purely symmetrical shape, but the proportions of the main part you hold are quite compact. It measures around 60mm in width where you actually grip it, which is only around 5mm wider than far more compact-looking mice, such as the Razer Cobra Pro.

As such, while the overall design here lends itself to relaxed palm grip use, where your whole hand drapes over the mouse, it feels a little small to use in this way for my hands (19.5cm from wrist to end of middle finger). Instead, it felt good to use in fingertip and claw grip for my hand size. The Logitech G502 X Plus is similar in that it’s narrower than you might expect, but it has a little more meat on it to support your palm.

Speaking of fingertip grip, though, this is where this mouse’s weight plays against it, as it weighs in at 113g with the cover plate on its underside or 111g without it. That’s a heavy mouse by modern standards, and sure enough, the Basilisk V3 Pro 35K feels far less nimble than ultralight mice that weigh less than half as much. Again, the G502 X Plus makes for a more direct comparison, though, as it also weighs over 100g – 106g to be exact.

This heft means that any gaming scenario where you’re using a low DPI and regularly pick up and reset your mouse during fast movements – i.e, playing competitive first-person shooters – feels like quite an effort on this mouse. It simply wouldn’t be one I’d recommend for players trying to find a competitive edge and reduced fatigue in those sorts of games.

Helping to alleviate the weight situation are patches of rubber on the sides of the mouse. These are nice thick patches – not just a soft-touch coating – and provide a really good grip, whatever the temperature or humidity level of your gaming space. Likewise, the scroll wheel has a nice, grippy, rubberized texture, and even the main left and right buttons and rear section of the mouse have a slightly rougher textured surface than some mice, so they’re reasonably grippy.

Software

Razer’s Synapse software is used to control all functions of the mouse, and it’s packed with features. In terms of core settings, you can reassign all the buttons other than left click to performance keyboard functions, mouse functions, switch profiles, set off macros, or act as the HyperShift button. The latter is where pressing that button switches the functions of the other buttons on your Razer gear. So, you can essentially assign two functions to every button.

The scroll wheel function can be changed to use the Smart-Reel feature, adjust its sensitivity, and enable the scroll acceleration where the freewheeling speed is faster than the notched speed.

Loads of DPI levels can also be assigned – a minimum of two, a maximum of five – and you can change the polling rate (with an option to change polling rate only when gaming) as well as calibrate the sensitivity to your liking. You can even set the lift-off distance and enable an asymmetric lift-off distance so the mouse stops tracking at one height and restarts at another.

Lighting can be turned on and off, and you can tap into the whole Razer Chroma lighting system for controlling all your Razer gear’s lighting. And, finally, you can adjust the standby time for the mouse to save power.

All of that, and you can record macros using the software, and it can detect the games you’re playing so that you can automatically trigger a different setup of your Razer gear for that game. I love the fact that some mice can do without software, but there’s no denying that, once configured, game-specific settings are useful.

Performance

As I touched on in the design section, the performance of this mouse for really competitive, fast-movement gaming with this mouse is limited by its high weight, and I generally find all the extra buttons on this style of mouse slightly get in the way in the heat of battle too. However, in terms of its raw sensor and switch performance, it can’t be faulted.

The maximum 35,000 DPI of the sensor is as pointlessly high as any mouse that has ever pushed beyond a DPI of about 8,000, but the Focus Pro 35K Optical Sensor Gen-2 does indeed provide effectively flawless tracking. You’ll need a quality surface to get the most from it – optical gaming mice don’t play well with shiny surfaces, for instance – so we do recommend buying one of the best gaming mousepads, but when used back-to-back with countless other modern, top-tier mice, the Basilisk V3 Pro 35K wants for practically nothing.

The only area where this mouse trails some others is in not offering 8kHz polling out of the box. However, while we have been able to detect a small benefit to polling rates as high as 4KHz, you’ll need at least a 240Hz monitor to notice, and, again, this ultimately isn’t a thoroughbred mouse for peak gaming performance, so it’s not a feature we missed.

Instead, the only performance issues we encountered with this mouse were around its battery life and a few day-to-day usability quirks. We’ll look at the battery life in the next section, but one factor is that the two main front buttons have edges that overhang the sides of the mouse, as opposed to having a little wall running along the edge of the mouse. I found I sometimes accidentally pressed the buttons more than usual, as my fingers had nowhere to rest other than on the sides/edges of the buttons.

Meanwhile, the cable is also not particularly lightweight, so although its nice that its braided surface is fairly tough, it pushes back against your mouse more than some. This makes it less easy to use the mouse accurately when connected to the cable while it’s charging.

The final little oddity is that I found the Hyperscroll function would sometimes just stop responding. Every once in a while, I’d come to use the mouse and it wasn’t working, so I’d have to power cycle it. This hasn’t yet happened in a tense time while gaming, but there’s the chance it could.

Battery life

Battery life on the Basilisk V3 Pro 35K is another factor that’s more middling than magnificent. Despite impressive claimed peak battery life figures of 140 hours on wireless and 210 hours on Bluetooth, I found this mouse running out of juice a little more often than I’d typically expect of a modern wireless mouse.

In particular, I found that plugging the mouse in for a quick top-up provided surprisingly little extra use, such that if you only plug in for 20 minutes when it has run low, you find yourself in a cycle of topping it up multiple times a day. You really do have to plug it in for several hours to get a full top-up, but once fully charged it will last around half a week of all-day use.

My usage was admittedly with the RGB lighting on but only set to 33 brightness out of 100 and with the auto-dimming feature enabled, which reduces the brightness while the mouse is actually in motion. I also make extensive use of the switchable scroll wheel, so the constant changing may also impact battery life.

Price

The Basilisk V3 Pro 35K price is $159.99, which makes it an undeniably expensive wireless gaming mouse. The likes of the Cherry M68 Wireless and Turtle Beach Burst II Air can be had for $60 less. However, there are plenty of other premium wireless mice of a similar price that include far fewer features, such as the Logitech G Pro X Superlight 2 and Razer Viper V3 Pro. Plus, its main rival, the Logitech G502 X Plus is, on paper, even more expensive at $179.99, though it’s regularly discounted to around $150.

Verdict

The Razer Basilisk V3 Pro 35K is a fantastic wireless gaming mouse for those seeking a rodent that can do nearly everything. Whether you want a mouse for travel and need Bluetooth, or you use your mouse a lot for work and need the fast scrolling, or you just need lots of buttons for macros, it has it all.

It’s also comfortable to use in a variety of grip styles and has excellent raw gaming performance with solid, if not exceptional, battery life.

However, its weight definitely holds it back for really fast movement, which limits its appeal for competitive gaming. Instead, it’s ideal for most other types of games and for work.

It’s a very close run thing as to whether I’d recommend this Razer or Logitech G502 X Plus overall. The Logitech has a few more buttons and I slightly prefer the shape, but the way the Razer’s scroll wheel switches is super convenient and it’s far quieter in use too – the Logitech sounds hollow and clunky.
