Build Quality

Overall build quality is solid. When shaking the mouse, a minor rattle comes from the scroll wheel. When applying lateral pressure, minor creaking but no 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 regardless of the set debounce time.

Buttons

Main buttons on the NP-01S V3 Wireless are good to very good. Pre-travel is moderate to high and post-travel is moderate, but button response is firm and snappy nonetheless. Despite being visually separated from the shell, button movement is nonexistent even when forced. Button stiffness is medium. A pair of Huano switches (blue transparent shell, pink plunger) are used for these.


Side buttons are excellent. Both pre- and post-travel are virtually nonexistent, resulting in a sharp and pleasing button response. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of surface-mounted Huano switches (white plunger) are used here.

A slider at the bottom switches between on- and off-state, which works fine.

Scroll Wheel

The scroll wheel is good. Noise levels are elevated, but tactility is good, with clearly separated steps allowing for controlled scrolling. The encoder comes from TTC (blue, yellow core), and has a height of 7 mm. The middle (scroll wheel) click requires medium to low force for actuation. An elevated, 2-pin low-profile switch from Huano (white plunger) is used for this one.

Surface

The NP-01S V3 Wireless 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 NP-01S V3 Wireless is easy. The Torx T6 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 to rip the cable connecting the two.

The internal design is identical to that of the NP-01S V2 Wireless. The main button switches and scroll wheel encoder once again sit on their own PCB, screwed to a plastic assembly also holding the side-button PCB, with both PCBs connecting to the main PCB through an FFC. The battery is placed on a sticky pad towards the rear. Three screws are used to affix the thin and mostly compact main PCB to the bottom shell. The MCU is a PixArt PAR2863FJ. Production date for the main PCB is December 31st of 2025, whereas the main-button PCB was manufactured on December 26th of 2025.


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