Build Quality

Overall build quality is very solid. There is no rattle when shaking the mouse. When applying lateral pressure, no creaking can be observed. It is impossible to activate the side buttons by squeezing the sides with any amount of force. Lastly, no accidental clicks occur when slamming the mouse down.

Buttons

Main buttons on the M808 Storm are very good. Both pre and post-travel are low, resulting in a firm and satisfying click response. Click feel is a bit dull and spongy, however. Button stiffness is medium. Huano switches (blue shell, white plunger) are used for these.


Side buttons are very good. They have some pre-travel, but post-travel is low, and the actuation point is even across the button. Button size and placement are good as actuation is possible rather easily by rolling one's thumb over these. The forward button has a riffle pattern, which makes it easier to distinguish from the other by feel. CF switches (red plunger) are used here.

At the top of the mouse are two buttons for cycling up and down through the set CPI levels. Click feel is decent. Another button for cycling through RGB lighting modes is at the top. Its click feel is decent as well. Huano switches (red plunger) are used for these. A button at the bottom of the mouse allows for profile switching.

Scroll Wheel

The scroll wheel is very good. Scrolling up is a bit noisier than scrolling down, but overall noise levels are quite low. The individual steps lack a bit of tactility, but not too much. The encoder is from F-Switch. The middle scroll wheel click requires low force for actuation—I do not know the brand of the switch.

Coating

While the sides of the M808 Storm are shiny ABS plastic, the top has a smooth matte coating. It's very grippy and 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, an excellent coatings.

Disassembly

Disassembling the M808 Storm is pretty easy. First, remove the mouse feet and unscrew the screws. Some force is then needed to separate the top and bottom shell as two clips keep the sides shut. Inside, we find a rather large, moderately thick main PCB. A moderately thick side-button PCB is screwed to the top shell and connected to the main PCB through a 6-pin JST connector. A smaller auxiliary PCB is attached to the scroll wheel for illumination. I'm not sure why a 4-pin connection is used for this. The whole PCB (well, most of it) is covered in a shiny coating, which makes it impossible to identify the MCU. Curiously, the main PCB is only clipped onto several plastic pins; the only screw belongs to the auxiliary PCB.


As for the soldering and general quality of the PCB, I'm unable to find any noteworthy flaws. There's some yellow gunk next to the sensor, however. From what I can tell it's not of the good-looking kind.
