Build Quality

Overall build quality is very 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 impossible. Lastly, no accidental clicks occur when slamming down the mouse.

Buttons

Main buttons on the Avior Pro are very good. There is a decent amount of post-travel on either button, but pre-travel is pleasingly low on both. The switches themselves provide a clearly defined and snappy response. The buttons can still be actuated quite far back on the mouse, though the shell imparts a high degree of rigidity in that case. Button stiffness is medium. A pair of Kailh GM 8.0 (80 M) switches is used.


Side buttons are good. On the left side, the back button has minimal post-travel, while the forward button has low post-travel, and both have some pre-travel. On the right side, the reverse is true, and the back button has more post-travel, while pre-travel is similar once again. Button response is equally snappy and pleasing on both. Button placement is good as actuation is possible very easily by rolling one's thumb across. A pair of TTC switches (red plunger) each is used here.

At the top of the mouse are two buttons for cycling up and down through the set CPI steps, which work just fine. Two TTC switches (old logo, blue plunger) are used for these.

Scroll Wheel

The scroll wheel is good. Scrolling in either direction is quite noisy, but tactility is decent, providing clearly discernible steps, although scrolling is a bit too light for my liking. Most notably, compared to other wheel designs, this one sits quite a bit lower, so that it barely sticks out. The encoder comes from ALPS (black core) and has a height of 9 mm. The middle (scroll wheel) click requires low force for actuation. Yet another TTC switch (white plunger) is used for this one.

Coating

The Avior Pro has a smooth matte surface all over. It doesn't attract fingerprints, dirt, or the likes too much. It is easy to clean, and there are barely any signs of wear left after doing so. All in all, very good materials.

Disassembly

Disassembling the Avior Pro is very easy. Just remove the rear skate and the screws beneath it, and pop the top and bottom shell apart. While the internal design isn't as inefficient as on the Naos Pro, saving weight clearly was no concern on this one either. The top and side buttons sit on their own PCB screwed into the top shell and are connected through a ribbon cable. An auxiliary PCB for illumination purposes can be found next to the scroll wheel. All PCBs are incredibly thick, and the main PCB in particular has a decent amount of unused space. Production date for the main PCB is the 49th week of 2020. Three screws are used to secure the main PCB to the bottom shell. The MCU is an STM32L072RBT6, whose datasheet can be found here.


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