Build Quality

Overall build quality is very solid. When shaking the mouse, there is a slight rattle coming from an indeterminable source. When applying lateral pressure, minor creaking but no flexing of the shell can be observed. Activating the side buttons by squeezing the sides is impossible. Lastly, accidental clicks do not occur when slamming down the mouse, irrespective of what the debounce time is set to.

Buttons

Main buttons on the Aria XD7 are very good. While the left one has low pre and moderate post-travel, the right one has low pre but no post-travel at all, resulting in a firm and snappy button response. The buttons are visually separated from the shell, but lateral button movement is minimal, and needs to be provoked. Button stiffness is medium. A pair of Kailh GM 8.0 (80 M) switches are used.


Side buttons are very good. Both pre and post-travel are low, resulting in a snappy and pleasing button response. The pressure point is mostly even across the entirety of these. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of Huano switches (white plunger) is used for these.

At the bottom of the mouse is a single button for cycling through the set CPI levels, which works just fine, accompanied by another button for Bluetooth pairing, which too works fine. The slider at the bottom switches between wired/off-state, 2.4 GHz wireless, and Bluetooth, this likewise works without issue.

Scroll Wheel

The scroll wheel is good to very good. Noise levels are elevated, but tactility is good, providing clearly separated steps and controlled scrolling. The encoder comes from TTC (yellow) and has a height of 13 mm. The middle (scroll wheel) click requires high force for actuation. Another Huano switch (blue plunger) is used for this one.

Surface

The Aria XD7 has a smooth 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 Aria XD7 is easy. The screws are located beneath the rear and front skates. The sides are additionally locked in with clips. As always, wedging a credit card or something similar in is the preferred course of action. When doing so, make sure not to rip the cable connecting the side-button and main PCB.

The design is reasonably efficient. The side buttons sit on their own PCB screwed into the top shell, which is connected to the main PCB through a ribbon cable. All PCBs are very thin, to save as much weight as possible. The battery is glued to a plastic tray, which is screwed in with three screws also serving to affix the main PCB to the bottom shell. The MCU is a CompX CX52850.


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