Build Quality

Overall build quality is solid. When shaking the mouse, a rattle comes from the main buttons. When applying lateral pressure, no creaking but minor flexing of the shell can be observed. Activating the side buttons by squeezing the sides is possible, albeit only if using excessive force. Lastly, accidental clicks when slamming down the mouse do not occur.

Buttons

Main buttons on the ZPW Max are good. Pre-travel is low and post-travel is very high, resulting in a fairly firm and snappy button response nonetheless. Being visually separated from the shell, button movement is moderate when provoked. Button stiffness is medium. A pair of Omron D2FP-FN2 (China) switches are used.


Side buttons are very good. Pre- and post-travel are low, and actuation is mostly even across the entirety of these, though feedback is much duller on the forward button. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of seemingly unbranded two-pin, low-profile switches (white plunger) are used for these.

At the bottom of the mouse is a button for cycling through the set CPI levels, which works just fine. A seemingly unbranded tactile switch is used for this one. A slider at the bottom switches between 2.4 GHz wireless, Bluetooth, and off-state, which also works fine.

Scroll Wheel

The scroll wheel is very good. Noise levels are mostly under control, and tactility is good, with the individual steps being well-defined. The encoder comes from TTC (blue, yellow core) and has a height of 13 mm. The middle (scroll wheel) click requires medium force for actuation. A seemingly unbranded tactile switch (blue plunger) is used for this one.

Surface

The ZPW Max has a matte surface all over. Grip is fine, and it doesn't attract fingerprints or dirt too much. It is easy to clean, and there are barely any signs of wear left after doing so. All in all, very good materials.

Disassembly

Disassembling the ZPW Max is easy. The screws are found beneath the front and rear skates. After removing those, four additional clips at the sides need to be dislodged, which is done rather easily. When separating top and bottom shell, make sure not to rip the cable connecting the two.

The internal design is reasonably efficient. The side buttons sit on their own PCB screwed to the top shell and connected to the main PCB through a ribbon cable. The battery is placed on a sticky pad towards the rear. Four screws are used to affix the thin main PCB to the bottom shell. The MCU is a Nordic nRF52840, whose datasheet can be found here. Production date of the side-button PCB is the 11th week of 2025.


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