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 for the back button, albeit only when using moderate to high force. Lastly, accidental clicks when slamming down the mouse do not occur regardless of the set debounce time.

Buttons

The main buttons on the AX Wireless are very good. Both pre and post-travel are moderate, but button response is firm and snappy nonetheless. Despite being visually separated from the shell, button movement is minimal even when forced. Button stiffness is medium. A pair of Huano switches (pink plunger) are used for these.


Side buttons are excellent (forward button) to decent (back button). Both pre and post-travel are very low, but when pressing the back button towards the rear, feedback becomes higher-pitched and duller, even though the pressure point continues to be mostly even. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of low-profile Huano switches (white plunger) are used here.

At the bottom of the mouse, three buttons controlling CPI, polling rate, and debounce time can be found, all of which also work fine. Three seemingly unbranded tactile switches are used for these. Lastly, a simple on/off-slider is present, which too works just fine.

Scroll Wheel

The scroll wheel is very good. Noise levels are somewhat elevated, but tactility is good, with clearly separated steps allowing for controlled scrolling without being overly stiff. The encoder comes from ALPS (black) and has a height of 7 mm. The middle (scroll wheel) click requires very high force for actuation. An elevated low-profile Huano switch (white plunger) is used for this one.

Surface

The AX Wireless 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 AX Wireless is somewhat difficult. Two Torx T6 screws are found beneath the rear skate, which need to be removed. The top and bottom shell can be separated now, but make sure not to rip the ribbon cables connecting top and bottom.

The internal design is reasonably complex. An endoskeleton is used, which has the PCBs for the top LEDs, side buttons, and main buttons along with the scroll wheel, all three of which are connected to the main PCB through ribbon cables. Removing the endoskeleton is only possible if the main buttons have been detached first. The sensor and MCU are located on the main PCB, which is affixed to the bottom with four screws. The MCU is a PixArt PAR2862QC.


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