Build Quality

Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, minor creaking but no flexing of the shell can be observed. Activating the side buttons by squeezing the sides is impossible. Lastly, no accidental clicks occur when slamming down the mouse, even with debounce time set to 2 ms.

Buttons

Main buttons on the MZ1 are excellent. Pre-travel is very low and post-travel is low, resulting in a firm and snappy button response. Button stiffness is medium. The button pieces are unusually long, covering more than half of the mouse body, yet actuation force is largely constant across their entire length. Minor lateral button movement can be provoked, but isn't noticeable during actual use. A set of Kailh GM 8.0 switches is used.


Side buttons are very good. Both pre and post-travel are low on the forward button, but the back button has some noticeable post-travel, and the actuation point isn't entirely even. Button response is firm and satisfying. Button placement is good as actuation is possible quite easily by rolling one's thumb across. Finding the right balance between button size and thumb space isn't easy on a mouse with such a low profile, so Xtrfy found a good middle ground here. A pair of Huano switches (yellow plunger) is used.

At the top of the mouse is a single button with varying functions depending on what the slider at the bottom is set to. Its click feel is good, and the slider works just fine. Another Huano switch (yellow plunger) is used for the top button. A button for cycling through the CPI steps is found on the bottom of the mouse, which too works fine. A seemingly unbranded tactile switch is used for this one.

Scroll Wheel

The scroll wheel is very good. Scrolling up or down doesn't produce much noise, but tactility is somewhat lacking, though still decent. The encoder comes from F-Switch. The middle (scroll wheel) click requires medium to high force for actuation. A seemingly unbranded tactile switch is used for this one.

Coating

The MZ1 has a smooth matte surface all over. It doesn't attract fingerprints, dirt, or the likes too much. It is easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.

Disassembly

Disassembling the MZ1 is easy. Remove all the skates and the screws underneath. Upon separating top and bottom shell, make sure not to rip the cable connecting the side-button and main PCB. The internal design is pretty simple. While the side buttons sit on their own PCB screwed into the top shell and connected to the main PCB with a 4-pin JST plug, everything else rests on the main PCB. The main PCB is fairly compact, with several LEDs distributed across the front and the big logo LED at the back. An auxiliary PCB next to the scroll wheel provides wheel illumination. Four screws in total are used to affix the PCB to the bottom shell. The MCU is a WTU301 N36C-C (2039-C), which previously has seen use on the Xtrfy M4/M42 as well as the Sharkoon Light² 100/200.


As for the soldering and general quality of the PCB, I'm unable to find any noteworthy flaws.
