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's impossible to activate the side buttons by squeezing the sides. Lastly, when slamming the mouse down, no accidental clicks occur.

Buttons

Main buttons on the A530 are good. Both pre and post-travel are low, yet the click feel leaves something to be desired. The buttons feel hollow, mushy, and simply not satisfying. Button stiffness is light. Omron D2FC-F-7N (20M) (OF) switches are used.


Side buttons are very good. Pre and post-travel are low, resulting in a firm and satisfying click feel. The pressure point is even across the entire button. Their size and positioning is good, which makes it easy to actuate them by rolling one's thumb over these. Kailh switches (red plunger) are used here.

At the top of the mouse is a single button which cycles through the set CPI levels. Its click feel is decent. A YSA switch (red plunger) is used for this one.

Scroll Wheel

The scroll wheel is good. There is no unwanted noise when scrolling, but the steps lack clear separation, resulting in below average tactility. The encoder comes from TTC. The middle (scroll wheel) click requires medium force for actuation. Another YSA switch (red plunger) is used here.

Coating

The A530 has a black matte coating on the sides and a rubberized coating on the top. Both coatings are very grippy, but the rubberized coating does attract dirt and finger marks quite a bit. After a bit of cleaning, barely any signs of wear are left. All in all, very good coatings.

Disassembly

Opening the A530 does not require removing the mouse feet. Instead, simply punch a hole through the sticker right below the bar code. Unscrew the screw and the two shells should be easy to separate. The internal design is simple as well. Instead of being screwed into the top shell, the side-button PCB is mounted onto the main PCB. All the PCBs are remarkably large, and the main PCB is noticeably thick as well. Going with smaller PCBs and "the side button screwed into the top shell" approach would have been a viable way to save some weight. The MCU is a WTU301 N360-C, which is known from the Xtrfy M4, Abkoncore A900, or Sharkoon Light² 200.


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