Build Quality

Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, no creaking or flexing of the shell can be observed. Activating the side buttons by squeezing the sides is possible by applying moderate force. Lastly, accidental clicks when slamming down the mouse do occur if debounce time is set to 5 ms or less.

Buttons

Main buttons on the GHERO Pro are good to very good. Pre-travel is moderate to high, and post-travel is low, resulting in a firm and snappy button response nonetheless. Despite being visually separated from the shell, button movement is low even when provoked. Button stiffness is medium. A pair of Huano switches (blue transparent shell, pink plunger) are used.


Side buttons are good. Pre-travel is low, but post-travel is high, resulting in a fairly satisfying button response nevertheless. The actuation point is even across the entirety of these. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of Huano switches (green plunger) are used for these.

At the top of the mouse is a button for cycling through the set CPI levels, which works just fine. Another Huano switch (green plunger) is used for this one. A slider at the bottom switches between on and off-state and is also used for polling rate adjustment, which works fine.

Scroll Wheel

The scroll wheel is decent. Noise levels are substantial, and tactility is merely average, as the individual steps aren't particularly well-separated. The encoder comes from TTC (blue, yellow core) and has a height of 10 mm. The middle (scroll wheel) click requires high force for actuation. Yet another Huano switch (green plunger) is used for this one.

Surface

The GHERO Pro 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 no signs of wear left after doing so. All in all, excellent materials.

Disassembly

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

The internal design is simple yet quite efficient. The top and side buttons sit on their own PCB screwed to the top shell and connected to the main PCB through a ribbon cable. An auxiliary PCB provides wheel illumination. The battery is stuck to the rear. Four screws are used to affix the very thin yet somewhat spacious main PCB to the bottom shell. The MCU is a PixArt PAR2862QN. Production date of the main PCB is the 11th week of 2024.


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