Build Quality

Overall build quality is very solid. There is no rattle when shaking the mouse. When applying lateral pressure, no creaking of the shell 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 Zephyr Gaming Mouse are very good. Post-travel is moderate, but pre-travel is very low, resulting in a snappy and pleasant click response. Button stiffness is light. Omron D2FC-F-K (50M) (China) switches are used for these.


Side buttons are very good. There is again some post-travel, but post-travel is low. The pressure point is even across the entire button. However, the buttons sit quite high, which can make it difficult to actuate these by rolling one's thumb over them. I don't know the brand of the switches (looks like a "W"?).

At the top of the mouse is a button for cycling through the set CPI levels. Its click feel is decent. The brand for this switch is the same as for the side-button switches.

Scroll Wheel

The scroll wheel is good. Scrolling up is quite noisy, scrolling down less so. The individual steps are nicely separated, resulting in good tactility. At times, scrolling up a single step wasn't registered properly by the mouse, which is quite annoying. The encoder comes from F-Switch. The middle scroll wheel click requires medium force for actuation. A Huano switch (green plunger) is used for this one.

Coating

The Zephyr Gaming Mouse has a matte coating all over. 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 coating.

Disassembly

Disassembling the Zephyr Gaming Mouse is fairly easy. First, remove all the mouse feet and unscrew the screws. Some caution ought to be applied when opening the mouse as the two ribbon cables going from the main PCB to the top shell can be ripped apart quite easily. The internal design is quite simple, actually. The fan is plugged directly into a header on the main PCB, and the side buttons and CPI button sit on their own PCB screwed into the top shell. The connector is soldered directly to the PCB, which I don't particularly like. Additionally, a small elevated PCB is attached to the scroll wheel for illumination. All PCBs are rather thin in order to keep the weight low. Production date for the main PCB is June 6, 2020. Unfortunately, I couldn't identify the MCU since it lacks any markings.


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