Build Quality

Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, minor creaking but no flexing of the shell can be observed. Activating the side buttons by squeezing the sides is possible but requires excessive force. Lastly, accidental clicks do not occur when slamming down the mouse irrespective of what the debounce time is set to within the software.

Buttons

Main buttons on the T.G.A. are very good. There is some pre-travel, and the left button in particular has noticeable post-travel, but the click feel itself is firm, snappy, and highly satisfying. While the buttons are visually separated from the shell, lateral button movement is low and needs to be provoked. Button stiffness is medium. Button spacers of various thickness are included in the box, which can be used to adjust the button response to one's liking. A pair of Kailh GM 8.0 (80 M) switches is used.


Side buttons are excellent. The back button has minor pre-travel, but other than that, there is virtually no travel, and the click feel is firm and snappy. The pressure point is 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 (yellow plunger) is used for these.

At the top of the mouse is a single button for cycling through the set CPI levels. Its click feel is good. Another Huano switch (yellow plunger) is used for this one. A slider at the bottom allows switching between off-state, wireless with lighting enabled, and wireless with lighting disabled, which too works fine.

Scroll Wheel

The scroll wheel is excellent. Scrolling up or down doesn't produce much noise, and tactility is great, providing clearly separated steps and highly controlled scrolling. The encoder comes from F-Switch (brown, black core) and has a height of 11 mm. The middle (scroll wheel) click requires medium to high force for actuation. Yet another Huano switch (blue plunger) sees use here.

Surface

The T.G.A. has a smooth matte surface all over. Grip is fine, and it doesn't attract fingerprints, dirt, or the likes 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 T.G.A. is easy. Remove the large rear skate and the two screws underneath. The front and sides are merely clipped in, but releasing those clips may require above average force. When doing so, make sure not to rip the cable connecting the side-button and main PCB.

The internal design is pretty simple. While the side buttons sit on their own PCB screwed into the top shell and connected to the main PCB with a 3-pin JST plug, everything else sits on the main PCB. The main PCB is surprisingly large, but fairly thin to save weight. Whereas the plastic assembly erected above the sensor held the weight system on the T.G.A. Wired, it holds the battery on the T.G.A., which connects to the main PCB through a 3-pin connector. Three screws and four pins in total are used to keep the PCB in place. The MCU is a CompX CX52850.


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