Build Quality

Overall build quality is solid. When shaking the mouse, a minor rattle comes from the scroll wheel and on/off-switch. 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, 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 LIX Plus Wireless are very good. There is a bit of pre-travel along with moderate post-travel on both buttons, but the button response 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. A pair of Kailh GM 8.0 (80 M) switches is used.


Side buttons are good to very good. The back button has significant pre-travel, and both buttons can be pushed in quite a bit past the actuation point. Button response, on the other hand, is pleasing, and 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 top of the mouse is a single button for cycling through the set CPI levels. Its click feel is very good. A seemingly unbranded tactile switch 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 good. Noise levels are mostly under control, and tactility is pretty good, providing fairly defined individual steps, but the wheel feels somewhat flimsy, for lack of a better word. The encoder comes from TTC (white) and has a height of 9 mm. The middle (scroll wheel) click requires medium force for actuation. Another Huano switch (white plunger) is used for this one.

Surface

The LIX Plus Wireless 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 LIX Plus Wireless is very easy. Remove the two rear skates and the two screws underneath. The front is merely clipped in, allowing one to easily separate top and bottom shell.

The internal design is very simple. The side buttons sit on their own PCB vertically mounted next to the main PCB and connected through a 3-pin connector. An auxiliary PCB next to the scroll wheel provides wheel illumination. The battery is placed atop a plastic assembly erected above the sensor. Everything else sits on the main PCB, which is moderately thin and affixed to the bottom with three screws in total. The MCU is a CompX CX52850.


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