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, accidental clicks when slamming down the mouse do not occur.

Buttons

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


Side buttons are good. While pre and post-travel are low, feedback isn't particularly pleasing, though the actuation 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 2-pin low-profile switches from TTC (brown shell, 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 at the bottom switches between on and off-state, which also works fine.

Scroll Wheel

The scroll wheel is good. Noise levels are above average, but tactility is quite good, with decently separated steps. 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 (black plunger) is used for this one.

Surface

The Hyperlight has a matte surface all over. Grip is fine, and it doesn't attract fingerprints or dirt too much. It can be difficult to clean, but there are barely any signs of wear left after doing so. All in all, good materials.

Disassembly

Disassembling the Hyperlight is easy. The screws are found beneath the front and rear skates. After removing those, two additional clips at the sides need to be dislodged, which is easily done. When separating top and bottom shell, make sure not the rip the cable connecting the two.

The internal design is highly efficient. The side buttons sit on their own PCB screwed to the top shell and connected to the main PCB through a ribbon cable. The battery is placed on a sticky pad towards the rear. Four screws are used to affix the thin and very compact main PCB to the bottom shell, which has been extended to the sides to aid with structural integrity. The MCU is a Nordic nRF52840, whose datasheet is found here. The Bluetooth capability of the chip remains unused. Production date for all PCBs is the 34th week of 2024.


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