I thought I was happy with my mouse. We explored many virtual worlds together, dispatched countless enemies, and played long into the night. Even after a full workday, its click and scroll were undiminished. It served me well. But that was before I got my hand on the Razer Basilisk Ultimate. This towering champion of the wireless gaming mouse world is in a whole different category. I never realized a humble mouse could be so exceptionally good.

The Razer Basilisk Ultimate is a wireless mouse with programmable buttons galore, a sharp, angular design featuring no fewer than 14 customizable lighting zones, and incredible sensitivity and accuracy. Radiofrequency (RF) technology provides a fast wireless connection that’s lag-free, and the Basilisk Ultimate comes with an angled charging dock. It’s a medium weighted, right-handed mouse that’s supremely comfortable to use.

The catch? It costs a whopping $170. I’ve been using it for a couple of weeks to find out if it can possibly justify that asking price.

With an angular design that’s all diagonal cuts and colorful LED lighting zones and a prominent Razer logo, the Basilisk Ultimate screams gaming mouse. This is a right-handed mouse with textured sides and a thumb rest on the left. At 107 grams, it’s a medium weight device, and it’s relatively large at just over 5 inches long and around 3 inches wide, if you include the thumb rest. 

I have large hands and I find the Razer Basilisk Ultimate extremely comfortable to use for long gaming sessions. It can accommodate a palm, claw, or fingertip grip, but it may not suit people with smaller hands or those who prefer a very lightweight mouse. 

The buttons have a satisfying click, and I haven’t experienced any misfires in my time with the Basilisk. The scroll wheel is excellent, with a wheel on the underside that enables you to fine-tune its resistance. As well as clicking down, you can tilt the scroll wheel right or left, which is a smart option that can prove very handy in the heat of combat (it scrolls by default, but you can remap it). 

There’s a paddle attachment for the left side, which is particularly useful for temporarily adjusting the sensitivity – if you’re into first-person shooters, you can hold down this paddle for more accurate aiming when you’re sniping. 

The Razer Basilisk Ultimate comes with its own charging dock, which also has LED lighting around the base. This dock has a couple of pins and the Basilisk connects magnetically when you’re not using it. The light reflects its charging state and the angle means the mouse resembles a mini desk sculpture when docked. I also appreciate that you can plug the dock into your PC and then plug the dongle into the dock, so only one port is required.

Setup and interface

You can plug the USB dongle into your PC and get started with the Basilisk Ultimate straight away, but you’ll want to install the Razer Synapse software, so that you can fully customize your new mouse. I found Synapse quite easy to use. You can remap every button and set up shortcuts and macros, you can also tweak the sensitivity of the five DPI presets, calibrate for your desktop, and customize a few other features.

If you want to set up specific profiles for different games or apps, you can do it in Synapse. There’s also onboard memory for five different profiles on the Basilisk Ultimate itself, which will prove handy if you frequently switch rigs.

To get the most from the LED lighting zones you also need to install Razer Chroma Studio. I found this a bit harder to master. Using the Basilisk Ultimate with a Razer keyboard it took me an embarrassingly long time to figure out how to get the same fire effect on the keyboard, mouse, and dock, but I got there in the end. The preset lighting effects are good and mostly easy to apply, but if you want to create your own there’s a bit of a learning curve.

Performance and features

While my response time is fading as I grow older, the Razer Basilisk Ultimate feels like a seamless extension of my in-game will. Razer’s optical mouse switches never miss a click. They employ an infrared light beam that offers a 0.2-millisecond response time. The polling rate goes up to 1,000Hz, and I found the wireless connection silky smooth. I didn’t encounter any lag in my time with this mouse. The DPI goes up to a ridiculous 20,000 maximum and can hit 650 inches per second. Suffice to say, this mouse performs beautifully.

The Razer Basilisk Ultimate served me well throughout a normal workday, but it really comes into its own when you fire up a game. From “Shadow of War” to “Doom” to “Rimworld” I found this mouse flawless. It feels accurate and fast and I never had a reason to question it. How much I’ve enjoyed using it became clearer when I switched to a different mouse for another review and found the change horribly jarring. My 11-year-old, “Fortnite”-obsessed son also tried out the Razer Basilisk Ultimate and really liked it, though he generally prefers a smaller, more lightweight mouse.

Razer suggests that you can expect up to 100 hours of battery life from the Basilisk Ultimate, but you’ll need an aggressive sleep mode setting and lighting turned off to achieve that. Even with lighting turned on, the only time the battery ran out on me was when I forgot to put it on the dock at night and had to plug in the following evening. Get into the habit of placing it on the dock at the end of each day and you’ll never run out of power. You can also plug the cable directly into the mouse to keep using it. 

The bottom line


Simon Hill/Business Insider

The Razer Basilisk Ultimate is a feature-packed, fully customizable wireless gaming mouse with a smart design and an eye-catching lighting system. It’s the most comfortable right-handed mouse I’ve ever used, the performance is flawless, and I love the charging dock.

Should you buy it? 

At $169.99, the Razer Basilisk Ultimate is outrageously expensive, and it’s undoubtedly overkill for most people, but it’s also supremely customizable, thoughtfully designed, and an absolute joy to use. If you don’t flinch at dropping that kind of cash on a mouse, I don’t think you’ll regret buying it. 

Which model should you get?

If you’re sold on the design, performance, and features here, but you can live with a cable and without the lighting, then the Razer Basilisk V2, at $80, will save you a good bit of cash. You can also get the Razer Basilisk Ultimate without the dock for $150. 

What are your alternatives?

The Logitech G502 Lightspeed, at $150, is perhaps the most obvious alternative. I also recommend checking out the Corsair Dark Core RGB Pro SE, which is comparable in terms of features, but costs a much more affordable $90

Pros: Excellent performance, fully customizable, comfortable to use, smart design, handy charging dock

Cons: Awfully expensive, no Bluetooth
