Build Quality

Overall build quality is mostly solid. When shaking the mouse, a clearly audible rattle comes from an indeterminable source. When applying lateral pressure, no creaking or flexing of the shell can be observed. It's impossible to activate the side buttons by squeezing the sides. Lastly, no accidental clicks occur when slamming the mouse down.

Buttons

Main buttons on the MoshPit WHM-01 are good to very good. Both pre and post-travel are low, resulting in a firm and satisfying click response. Despite lacking much wiggle room, the buttons are slightly loose, however. Button stiffness is medium. Huano switches (blue shell, white plunger) are used.


Side buttons are good. There is a decent amount of pre and post-travel, and depending on where the buttons are pressed, pre-travel skyrockets (beyond the stratosphere). In general, the pressure point is not even across the entirety of these. The click feel itself is quite pleasing, though. Button size and placement are good as actuation is possible rather easily by rolling one's thumb over these. I do not recognize the brand of these switches.

At the top of the mouse is a button for cycling through the set CPI levels. Its click feel is good. I can't quite recognize which switch is used for this one. At the bottom of the mouse is a slider that switches between off-state, wireless, and eco-mode. The button next to it switches through the RGB lighting effects. Both work perfectly fine.

Scroll Wheel

The scroll wheel is good. Scrolling in either direction is quite noisy, but the individual steps themselves are fairly well defined, resulting in above average tactility. The encoder comes from F-Switch. The middle (scroll wheel) click requires medium to high force for actuation. Again, I'm unfamiliar with this switch brand.

Coating

The mouse is entirely covered in a smooth, matte white coating. It doesn't provide a lot of grip, but doesn't attract fingerprints, dirt, or the likes too much. It's easy to clean, and there are no signs of wear left after doing so. All in all, a good coating.

Disassembly

Disassembling the MoshPit WHM-01 can be tricky. First, remove the two rear skates and the screws underneath. Then, wedge a credit card between the top and bottom shell to dislodge the two clips located below the two side buttons on each side. The internal design is simple and efficient. The side buttons are soldered directly to the PCB, although slightly elevated. The side-button mechanism pushes down on them at an angle, which seems to be working surprisingly well. The top CPI button too is located on the PCB and actuated by a very long stem. An auxiliary PCB next to the scroll wheel provides wheel illumination. The main PCB is fairly large and thick, so the weight could have been brought down substantially by slimming things down a bit. Two bottom-mounted hooks keep the main PCB in place, along with two additional screws. The MCU is a Sinowealth SH68F 1000S. Please refer to this for more information.


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