Review: Corsair Sabre V2 Carbon Fiber and Magnesium Gaming Mice is currently attracting attention in the technology world.
Experts believe this development may influence how digital platforms evolve
over the coming years.
The topic has already sparked discussions among developers, analysts,
and industry observers who are closely monitoring how the situation unfolds.
Carbon fiber and magnesium are typically relegated to the world of high-performance automotive engineering. Both are known for being incredibly lightweight while maintaining an incredible amount of stiffness and rigidity. While neither of them have traditionally had a place in the world of computer peripherals, they’ve slowly crept into the space over the past few years.
Carbon fiber mice have been around for quite a while, although they’ve typically only been offered by smaller brands with a significant focus on competitive gaming. Magnesium, meanwhile, was also offered by Razer with their Viper Mini Signature Edition, which featured a full magnesium shell and retailed for nearly $300.
Corsair has now entered the space with two new versions of the popular Sabre V2. The two are nearly identical, with the only real difference being the top shell (the carbon fiber version also includes a small carrying case). The two include the same accessories: A 2.4G dongle, a USB-C cable, and a set of larger mouse feet.
The magnesium version retails for half the price of Razer’s limited-run magnesium mouse, at $150, while the carbon fiber version is $200. Because of this, both mice are surprisingly competitive with other brands’ flagship offerings. Should you be interested in a mouse made out of cool materials now that they’re not twice as costly? After testing both of them, I think you should.
When I reviewed the standard Sabre V2 Pro Ultralight, I loved the weight, but I didn’t love the build quality. It was an impressively light mouse, tipping the scales at only 36 grams, but because of that, it felt fragile. The plastic flexed when squeezed and was so thin that, if I wanted to, I could have crushed it with my bare hands. This was great if you wanted the absolute lightest mouse possible, but was less-than-ideal for anyone seeking something that felt durable or premium.
With both of the Sabre v2’s new versions, this is not an issue at all. These mice are rigid. Both magnesium and carbon fiber have been tested thoroughly in the world of motorsports, and proven beyond a doubt to be able to withstand force far greater than even the most powerful gamer rage. Even using the full force of my grip, neither of the shells wanted to flex at all.
By opting for either of these mice, you gain around 20 grams of weight, with the carbon fiber and magnesium coming in at 55 and 56 grams, respectively. The result is a mouse that feels more rigid than its competitors. The Razer Viper v3—weighing 55 grams, with an MSRP of $160—doesn’t have the same sturdiness. That said, the difference is absolutely marginal; the Viper v3 is still a solid mouse at a similar build quality that feels great in hand.
This somehow demonstrates both the strongest advantage and greatest downfall of using these engineered materials for a mouse: Plastic has enough rigidity already (the only exception being what Corsair did before, making the mouse as thin as possible to make it as light as possible). Both carbon fiber and magnesium are incredibly lightweight when compared to steel and aluminum while maintaining comparable stiffness, and that’s useful in motorsports, but these materials are clearly overkill for a gaming mouse. What makes them special is that they’re appearing now at this price for the first time. If you can have carbon fiber, why not?
The magnesium model is available in both black and white. The white model I received has a subtle speckled texture across the metal surfaces. It feels slick and cool to the touch, much like any other metal would. The most divisive part is the massive cutouts in the shell, presumably for that last bit of weight savings. The larger gaps mean dead skin is less likely to build up around the edges of these holes, an issue I have encountered when using mice with hexagon-pattern cutouts for longer periods of time (like the Steelseries Aerox 3). The braces are positioned in a way that supports the hands well, but if you tend to rest your hand’s full weight on your mouse, you’ll likely find small indents left in your palm after extended use.
If you don’t want to deal with the skeletal remains of a mouse, carbon fiber might be the better option. With no weight-saving holes to be seen, the outer shell is a perfectly-smooth and familiar complex curve. The carbon fiber weave’s pattern stretches across the entire surface of the mouse, creating a dry texture and a satin-like finish. Between the two, I found the carbon fiber marginally more comfortable for regular use.
As far as actual ergonomics, the two are practically identical. They share the same bottom half, a slightly larger version of the original Sabre v2’s underside that adds a DPI button and a Bluetooth option to the power slider. Both are the same height (38.7 mm), width (59.5mm), and length (122.5 mm), with identical side button and mouse wheel placement. This makes them very slightly smaller than both the Viper V3 Pro and Logitech Superlight, but still suited to medium and large hands and comfortable for even long-term use.
The shape is neutral and nearly ambidextrous: Both halves of the mouse are identical, save for the buttons on the left-hand side. Button placement feels natural for palm, fingertip, and claw grips. The peak of the hump is placed slightly behind the center of the mouse, and the wheel placement is right where you’d expect, easy to reach with any grip style. Both sides taper in slightly towards the bottom, allowing for the mouse to easily be lifted up and moved during use. Really, there is nothing groundbreaking or particularly disappointing about the shapes of these mice. If you’re coming from another standard-shape mouse, you likely won’t have any issues.
With an 8,000 Hz polling rate, these mice are both on par with practically every other pro-grade gaming mouse available today, sending 8,000 messages every second. Both of them are set to a measly 1,000 Hz by default, which is still more than enough for nearly every use case outside of top-tier competitive lobbies.
During my testing, these mice felt responsive and snappy, with the sensor holding up to pretty much everything and never missing inputs. The two main buttons might be a bit light for some heavy-handed gamers, but have a crisp “click” and short travel distance that’s both responsive and enjoyable without being overstated.
Both of these mice come with two sets of feet: A smaller, arc-shaped set installed from the factory, and a larger, semicircle-shaped set. Like with the Sabre v2 Pro, I have no clue why these mice come with the smaller feet installed from the factory when the larger ones feel more stable, smoother, and easier to control. I can only guess it’s done to marginally reduce the published weight.
The other major improvement on these mice is the inclusion of Bluetooth connectivity. The original Sabre v2 Pro was 2.4G-only, a decision that was likely made to save a gram or two of weight and reduce complexity. Since these mice both have less of a single-minded focus on weight savings, with more emphasis on usability and build quality, they can connect to your computer without any need for the awkward USB-C dongle. This means they’re both great options for a portable gaming mouse. This is especially true for the carbon fiber model, which includes a hard carrying case in the box.
Corsair has upgraded from their iCue software to their new in-browser “Web Hub” software. I typically dislike moving from locally-installed software to web-based, since it poses risks to long-term support, but the lack of software running in the background and stealing processing power is often worth the tradeoff. As far as customization software goes, Corsair does a good job with its new Web Hub. Nothing stands out as great or ground-breaking, but nothing stands out as bad, either. Setup is simple, customization is seamless, and all the settings are in logical locations (although I wish the adjustment for polling rate was on the default page instead of only being under the “device settings” pop-up menu).
With Web Hub, the DPI button on the underside of the mouse can also be customized. Both the number of stages and DPI of each one can be adjusted, with up to five possible stages ranging from 100 DPI to 33,000. Each stage is color-coded, with the singular LED between the two mouse buttons illuminating to indicate which stage is active.
Both of these mice share nearly the same construction: A top half made from an exotic material, a bottom half made from plastic, a main motherboard attached to the bottom shell that contains the scroll wheel, mouse buttons, and battery, and a secondary board attached to the top shell that houses the two side buttons and LED power indicator. The two halves are attached together using plastic clips around the edge of the shell, which are then screwed together in four spots underneath the mouse feet.
While this assembly works well and allows for the mouse to be incredibly lightweight and rigid, I found a few concerns with repairability. With both shells, there is a risk of repeated disassembly breaking the plastic clips. With the carbon fiber shell, there is also a risk of the threads in the upper shell becoming stripped if the screws are over-tightened, something that is made worse by the fact that the screws used are self-tapping.
Typically, anything made from carbon fiber or lightweight plastic would use metal inserts inside of the material to prevent stripping, but this has not been done with this mouse—presumably also for weight savings. Because of this, half of the screws in this mouse already had material lodged between the threads during my initial disassembly, seemingly having already been over-tightened by the factory. This doesn’t impact usability, since the mouse is primarily held together by the plastic clips, but it could cause issues later down the line if the plastic clips fail.
I did actually break one of these plastic clips when disassembling the carbon fiber mouse. While I’m sure there is a way to disassemble this that avoids most risk, it does show that it can easily happen, even to someone with a lot of experience dissecting mice. I was able to superglue the broken section back together without any issue. When testing the mouse with a broken clip, I found it to feel more wobbly than before, and this wobblyness went away after the repair.
While repairability isn’t perfect, I don’t anticipate it causing many issues with these mice. They are dead simple internally, and don’t have much that can fail. Assuming you use one of these for a few years and the battery needs to be replaced, it’s unlikely that taking it apart once to replace the battery will render it irreparable.
These two mice are both competitively priced with current offerings from Logitech and Razer, while offering improved build quality and materials. They have nearly identical weights, while feeling more rigid than their competitors and with a more premium look.
The only real downside of these mice is the internals: While they boast competitive specs, both still use standard mechanical switches compared to Razer and Logitech’s optical switches. This likely won’t be an issue for the average user, since modern mechanical switches still have exceptional performance and impressive longevity.
Overall, I really recommend either of these models. The original Sabre v2 Pro Ultralight was a great mouse, but its lightness was a double-edged sword. In upgrading the materials, Corsair has both addressed this problem and elevated the mouse significantly, making two models that are not only functional, but also impressive demonstrations of material science that truly feel special.
Which model you choose is ultimately down to preference, but either of these mice will be serviceable in your gaming arsenal.
