Build Quality

Overall build quality is solid. When shaking the mouse, a rattle comes from the side buttons. 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 when slamming down the mouse do occur, provided debounce time is set to 2 ms or less.

Buttons

Main buttons on the L7 Pro are good to very good. Pre-travel is low and post-travel is high, resulting in a firm and snappy button response. Being visually separated from the shell, button movement is low when provoked. Button stiffness is medium. A pair of D2FP-FN2 (China) switches are used.


Side buttons are very good. Pre- and post-travel are low, but feedback is hollow and not particularly satisfying. The actuation point is even across the entirety of these nevertheless. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of low-profile, 2-pin TTC switches (brown, blue plunger) are used for these.

At the bottom of the mouse is a button for cycling through the set CPI levels, which works fine. A seemingly unbranded tactile switch is used for this one. A slider switching between 2.4 GHz wireless, Bluetooth, and off-state is also found at the bottom, which works fine.

Scroll Wheel

The scroll wheel is good to very good. Noise levels are mostly under control and tactility is above average, as the individual steps are rather well-separated. The encoder comes from TTC (blue, yellow core) and has a height of 9 mm. The middle (scroll wheel) click requires high force for actuation. A seemingly unbranded tactile switch (blue plunger) is used here.

Surface

The L7 Pro 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 barely any signs of wear left after doing so. All in all, very good materials.

Disassembly

Disassembling the L7 Pro is easy. First, all skates as well as the screws beneath them need to be removed. In addition, five clips at the sides and rear need to be dislodged, which is quite easily done, but some caution is advised to prevent ripping any cables when separating top and bottom shell.

The internal design is highly efficient. The side buttons sit on their own PCB screwed into the top shell and connected through a ribbon cable with the main PCB, whereas the battery is stuck to the rear. The main PCB is very thin and compact, and affixed to the bottom with four screws. The MCU is a Realtek RTL8762GKH, whose datasheet is found here. Production date for all PCBs is the 42nd week of 2024.


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