The Carbon X Review — Epomaker’s High-Performance Carbon Fiber Experiment

Epomaker just dropped something unexpected — a carbon-fiber gaming mouse. The Carbon X looks like it was built in a wind tunnel, mixing that premium supercar vibe with gamer DNA. It’s light, sleek, and feels way more serious than what you’d expect from a brand mostly known for keyboards. Let’s see if it performs as good as it looks.

Design and Build Quality

When I first read about this mouse, I was curious how Epomaker would manufacture a gaming device made out of carbon fibre materials. There are many gaming mice nowadays that don’t want to be “boring” and find new niches to sell their products, and it seems this is one of the ways.

This is a symmetrical mouse, slightly curved at the sides, with very nice finger grooves at the main clicks, with an open bottom, and some quite big honeycomb holes. The hump is placed directly in the middle. Actually, apart from the holes, it strongly resembles Lamzu Maya X. This one indeed is built of carbon fibre, a material that is stronger than plastic and lighter than aluminum. Carbon is also stronger against heat and temperature, which can be important to the mouse’s internals. The use of material should also protect the mouse from flexing and creaking, which can eventually lead to it breaking under pressure.

And that is definitely the case here. Even though the mouse has honeycomb holes, it is very sturdy, and try as I might, I couldn’t get it to flex. The mouse looks really premium when you look at it, a feature not often seen in this price range. The quality is something you can’t complain about, so I think you will be amazed when you get a grip of this one.

Bottom line — very high build quality, carbon fibre materials are great too.

Shape and Grip

Lamzu’s Maya Fanatic edition was one of the best mice in 2024, making its successful story among many gamers. No wonder Carbon X tries to take some of the Maya’s best features and pack them in its own way.

This is a fairly universal grip among symmetrical mice, something I’d call another “gold standard” besides the “potato” shape coined in 2025 by Logitech. It’s a slightly shorter and generally smaller Maya, a bit heavier though; however, if you strip the stock skates down and place 4 dot stakes there, the weight hovers at 45 grams (normally, around 47 grams, so lower than advertised).

The mouse can be gripped in many styles, including my relaxed claw/finger tip grip. However, I have to say that it was slightly too small for my 21×12 cm hand, making me feel a bit uncomfortable and struggle with some moves sometimes. I just missed a few more millimeters here and there, which made me fumble with the shape a few times.

Overall, it’s not the best pick for bigger hands, but small/medium hand users will feel immediately at home, especially those who use a claw/finger tip grip, because the mouse is a bit front-oriented.

Bottom line — small and medium hand users will love it, the gamers with big hands should reconsider.

Buttons and Clicks

Epomaker decided to go with Omron optical switches (main buttons) with Carbon X, and it seems it has paid off. Mouse1/2 buttons offer very short pre-travel, crisp tactile feedback, and very good spammability. There’s only a very small amount of pre-travel on mouse 2, but it’s nothing of serious concern. The tone is quite low, definitely less metallic/plasticky than other optical switch implementations — so, this implementation should satisfy a lot of users.

Side buttons use mechanical switches and are good overall. There’s a larger amount of pre-post travel compared to the main ones, but that’s to be expected. I guess the Razer’s side button implementations are still the gold standard.

The buttons on the main clicks have very nice grooves that keep your touch much closer to the switches than usual, and I find it also a very positive thing. The side buttons are placed well, and you don’t accidentally spam them when not needed. The scroll wheel is very tactile, not too light, not too hard to press, and seems very solid overall as well.

Bottom line — very good Omron opticals, very professional button design as well.

Coating and Skates

The coating on Carbon X is quite commendable in general, and many users and reviewers like it. However, I find it hard to evaluate because, to me, it is a bit slippery. Don’t get me wrong — it provides some sort of grip, some even would say it reminds them of silicone/rubber coating, and at the same time it’s smooth, but to me it doesn’t work too well, probably because the mouse is a bit too small for me, and I found myself fumbling with it. If it were bigger, I would probably have had no issues with it because it would have naturally stayed close to my palm. Remember, your experience may vary.

The skates are black teflon feet, quite thin, not rounded, and quite fast. I don’t think they are bad, not great either, just decent. Swapping them to 4 dots cuts the weight to 45 grams.

Bottom line — coating could be better, so could the skates.

Sensor and Software

The sensor used in Carbon X is the most popular Pixart 3950, the industry’s standard these days. All I can say is that it performs flawlessly, tracking is accurate and consistent, no spin-out, jitter, or hiccups, even at higher DPI levels. The sensor is very responsive, and it has a low latency of 0.4 ms in wireless 2.4gHz mode and around 0.35ms wired — so it’s only around 0.3ms behind the fastest performers. But let’s be real — this is just a number, and 99.99% gamers won’t see the difference.

The large polling rate of 8k is great on paper, but diminishing returns apply — your system, USB bus, OS, and game engine must support that kind of rate to actually benefit. For many users, 1000Hz is already plenty. I personally tend to game with 2k these days — it’s enough and it saves battery life.

The web-based software is here.

And this web driver does its job very well. Apart from the fact that you can’t rebind the side buttons, all other features are working well and provide all you need. Profiles, debounce time, LOD settings, Motion Sync, Performance Mode, Angle Snapping, Ripple Control, macros — all are there.

I know that the software for Pixart 3950 is capable of doing even more, but what we get is quite enough — not every software for this sensor is on par with RAMW or Rapoo.

Bottom line — decent software, no major complaints.

Battery Life

Unfortunately, this is my main complaint with Carbon X — the advertised 90-hour battery life holds pretty true, but that’s only on 1k polling rate. When you increase the polling rate, the battery suffers a disproportionate hit — no matter if you use 2k, 4k, or 8k, it usually dies after 2 days of heavy use (approximately 25 hours). I’d for 8k is a good result, but I don’t understand why it lasts pretty much the same on 2k and 4k. I suspect that it’s a problem with the encoder — many brands forget or neglect to choose a good Nordic encoder, both for the mouse and the dongle.

Logitech’s battery life is still the gold standard in this category.

Bottom line — above 1k polling rate, the battery life gets a strange hit.

Summary

Epomaker’s experiment with this carbon fibre gaming mouse is definitely a success. I like how they approach the design and overall build materials selection, and I really like this trend of making the mice more beautiful and cool-looking. Carbon X is definitely the pretty one in the bunch, and with its looks, there are also really good features that are packed inside — it definitely has almost everything you want from a modern mouse. Perhaps the weight could be stripped down a bit — high 30s would be excellent, and the battery life at higher polling rates should definitely last longer. But other than that, I don’t see anything that should actually keep you away from checking this mouse out — if you like the shape, of course, and you are more into faster games, because its design excels in that (for TacFPS I would consider something else).

This is actually Epomaker’s second gaming mouse, and while the Click Mouse (that I have reviewed as well) was decent, this Carbox X steps up and places Epomaker on the gaming mouse territory map with a bang.

Bullet Points

• Great-looking mouse
• Actually close to Lamzu Maya Fnatic edition in shape
• very solid carbon build, no creaks or flex
• The weight is slightly below 50grams, can go down to 45g with dot skates
• The sensor is flawless
• The medium and small hand users will love this mouse; the big hand users may have some gripping issues
• Very good implementation of Omron opticals on the main buttons
• The skates are just ok
• So is the software
• The coating feels a bit rubbery and smooth, but it was not working for me
• The battery life takes a big hit above 1k polling rate
• But the value-to-price ratio is good on this one, and it’s worth recommending
