YUNZII made its name with mechanical keyboards, but the company has recently started expanding into gaming mice as well. The YUNZII M2 is its latest model, and compared to the earlier releases, the specifications have taken a noticeable step forward. It comes equipped with a PAW3395 sensor, dual 8K polling, tri-mode connectivity and weighs just 63 grams.

At $35 (early bird price, regularly $49), the M2 finds itself competing in a crowded market. That’s the price range where plenty of good options already exist, so a strong spec sheet alone isn’t enough. I’ve been using the M2 as my daily mouse for the past couple of weeks, both for gaming and everyday work, to see whether it delivers where it actually matters.

Build Quality & Ergonomics

The M2 is off to a good start in terms of build quality. Its shells are made from a lightweight yet rigid plastic with a carbon-fibre texture. The texture is smooth but it’s enough to give the mouse a better grip, in addition to being resistant to fingerprints.

First impressions when holding the mouse are very good. It doesn’t feel cheap or flimsy in any way. There’s absolutely no flex or creaking, even during frantic gaming sessions.

In terms of shape, the M2 is similar to a Razer Viper – it’s symmetrical and has a low profile, making it ideal for flick shots and rapid movement. The sides taper in just enough to provide a secure hold, while the modest weight (63g) makes it easy to lift and reposition without effort. It’s a shape that favours claw and fingertip grips, though those with medium-sized hands should also find it comfortable for a relaxed palm grip.

I should note that I found the sides of the mouse a little too smooth to get a really firm grip at first, possibly because of my larger hands. I ended up applying the included grip tape to the sides, which completely solved the issue. As a bonus, I actually think the mouse looks even better with the grip tape installed.

Buttons & Switches

The main buttons on the YUNZII M2 feel really good. The optical switches have a nice tactile click with a satisfying amount of feedback, and while the clicks are audible, they aren’t loud or distracting. They feel responsive without being overly light, which is something I tend to prefer on a gaming mouse.

The side buttons are also well positioned and easy to reach. The clicks have a clean action with no noticeable mushiness or spongy feeling, and they don’t require much effort to actuate. The rubberised mouse wheel is another area where the M2 does well. It scrolls almost silently, but still has a clear tactile bump between steps, giving it a good sense of control without feeling rough or overly mechanical.

On the underside of the mouse, you’ll find the DPI switch, which cycles through the six available settings. I found 2400 DPI to be the most comfortable for me, but it’s good to know that all of the DPI levels can be customised through the web customiser if you prefer different settings.

The input selection switch is located here as well, allowing you to switch between the three connection modes: wired, 2.4GHz wireless and Bluetooth.

Sensor Performance

The PAW3395 sensor performs very well. Tracking is accurate and I never experienced any unwanted behaviour during testing, even with fast swipes across the pad. I also didn’t notice any difference between wired and wireless use; both felt equally consistent.

I left the lift-off distance at the default 1 mm setting, which I think will suit most gamers. If you prefer a little more height before tracking cuts out, the web customiser lets you increase it to 2 mm. All other settings were left at default, including the 8000Hz polling rate.

Wireless Performance & Battery Life

The wireless performance of the YUNZII M2 has been consistently good. I didn’t notice any latency or any difference in responsiveness compared to using it wired, and it remained reliable throughout my testing.

Setting up wireless mode is about as simple as it gets. The included dongle is stored underneath the rear mouse foot, which attaches magnetically to the underside of the mouse. Just plug it into your PC or laptop, flick the switch underneath the mouse, and you’re ready to go.

YUNZII rates the battery life at around 50 hours, and that seems fairly accurate in practice. This is most likely helped by the lack of RGB lighting, which is something I actually appreciate. RGB might look nice, but personally, I’d rather have better battery life on a wireless mouse. Furthermore, if you drop the polling rate down from 8000Hz, you can extend the battery life even further. It’s also worth noting that many gaming pros still use 1000Hz, so the higher polling rate isn’t necessarily something everyone will need.

Cable

The included cable matches the colour of the mouse, which in my case is the orange version, and I have to admit it looks cool. It adds a nice bit of visual consistency and feels like more thought has gone into the overall presentation.

Unfortunately, the cable itself isn’t quite as impressive. It’s very stiff and also quite heavy, which makes it awkward to use while the mouse is connected. It’s perfectly fine for charging, but I wouldn’t want to use it for gaming, and even moving the mouse around the desktop with the cable attached can be a little frustrating.

I’d much rather see a lighter and more flexible cable included. Something that you can plug in when the battery is running low and continue using the mouse comfortably without really noticing the cable is there.

Feet/Skates

The YUNZII M2 uses a simple two-foot design, with one large skate at the front and another at the rear. Despite the minimal approach, they glide smoothly across the mouse pad and I don’t have any complaints about the tracking or overall feel. They provide enough consistency for both gaming and general desktop use.

Software

The M2 can be customised using YUNZII’s online configurator. It’s fairly basic but lets you easily change things like lift-off distance, DPI settings and polling rate, as well as set up macros.

Gaming Performance

I found the M2’s gaming performance to be very good. Admittedly, I had some issues with the sensor tracking at first, but I fixed that by attaching the dongle to the cable and moving it closer to the mouse instead of plugging it directly into the back of my PC. Once that was sorted, I didn’t have any more problems, and the mouse responded perfectly.

The buttons didn’t give me any reason to complain either. The main switches have a responsive, tactile click, while the side buttons are positioned well enough that I never had any trouble finding them in-game. More importantly, I didn’t experience any accidental presses or misclicks throughout my time with the M2.

Everyday Use

The M2 is also a great mouse for everyday use. One thing I particularly liked is how quickly it wakes up from standby mode, with the cursor responding almost instantly. Whether I was browsing the web, replying to emails or just getting through my usual photo and video editing workload, the M2 remained comfortable in the hand and never gave me any problems.

Verdict

I’ve really enjoyed using the M2. I like the shape, and the smooth carbon fibre texture with its matte finish gives it a really nice feel in the hand. Add in good gaming performance, decent battery life and a low price, and it’s a mouse that’s easy to recommend.

The only thing I’m not a fan of is the cable. It’s quite stiff and feels a little heavy, which makes wired use less appealing. If you plan on using it wirelessly, though, the M2 is a great performer and offers a lot of performance for the price.
