Build Quality

Overall build quality is very solid. When shaking the mouse, a minor rattle comes from an indeterminable location. 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 F01 are good to very good. Pre-travel is moderate to low and post-travel very low, resulting in a fairly firm and snappy button response. Being visually separated from the shell, button movement is low when provoked. Button stiffness is medium. A pair of Kailh GO optical switches are used.


Side buttons are good. Pre and post-travel are low, but feedback is high-pitched and far from pleasing. 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 surface-mounted switches from Kailh (green plunger) are used for these.

At the bottom of the mouse is a button for cycling through the set CPI levels, which works just 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 very good. Noise levels are mostly under control, and tactility is good, with distinct steps allowing for controlled scrolling. The encoder has Pulsar branding, but comes from F-Switch (blue, red core), and has a height of 14 mm. The middle (scroll wheel) click requires high force for actuation. An elevated switch from Kailh (black plunger) is used for this one.

Surface

The F01 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 no signs of wear left after doing so. All in all, excellent materials.

Disassembly

Disassembling the F01 is easy. The screws are located beneath the rear skate. After removing those, six clips placed at the sides and front also need to be removed, which can be done quite easily. Caution needs to be applied when separating the top and bottom shell to avoid ripping the cable connecting the two.

The internal design is highly efficient. The side buttons sit on their own PCB screwed into the top shell and connected through an FFC to the main PCB. The battery is stuck to the bottom towards the rear. Everything else sits on the very thin and compact main PCB, which has been affixed to the bottom with six screws in total. The MCU is a Nordic nRF52840, whose datasheet is found here. The Bluetooth capability of the chip remains unused.


As for the soldering and general quality of the PCB, I'm unable to find any noteworthy flaws. Of particular interest, however, is the antenna construction, which is quite unlike anything I've seen before.
