Build Quality

Overall build quality is solid. When shaking the mouse, a rattle comes from the main buttons. When applying lateral pressure, no creaking or flexing of the shell can be observed. Activating the side buttons by squeezing the sides is possible but requires excessive force. Lastly, accidental clicks when slamming down the mouse only occur if debounce time is set to 0 ms.

Buttons

Main buttons on the Model I 2 Wireless are very good. Both buttons have moderate pre-travel, whereas post-travel is low on the right and nonexistent on the left button. Button response is very firm and snappy. Despite being visually separated from the shell, button movement is low even when provoked. Button stiffness is medium to heavy. A pair of Glorious-branded switches, which are modified Kailh GM 8.0 (80 M), are used here.


Side buttons are poor. The front side button has moderate pre-travel, and post-travel is merely moderate as well. Both the middle and back side buttons have high pre-travel, with the middle one being the greater offender, but whereas the middle button also has high post-travel, the back button only has moderate post-travel. The sniper button is the only one without copious amounts of travel, with pre-travel being very low and post-travel moderate. The three side buttons bulge outward significantly, which makes it easier to tell them apart by feel, but does make actuation by rolling one's thumb across more difficult. Huano switches (green plunger) are used for all of these.


The sniper and back side buttons are magnetic and can be swapped for a higher or lower profile alternative. With the latter installed, the button can no longer be actuated, which can be useful if their placement is found to be irritating. Moreover, an additional alternative sniper button essentially reverses its orientation, the purpose of which eludes me. Removing the magnetic side buttons without an external tool can be difficult, which is why such a tool is included, though even with that one it can be tricky.

At the top of the mouse are two buttons for cycling up and down through the set CPI levels, both of which feel fine. A pair of low-profile switches from Huano (white plunger) are used for these. A slider at the bottom switches between 2.4 GHz, Bluetooth, and off-state, which also works fine.

Scroll Wheel

The scroll wheel is very good. Noise levels are elevated when scrolling up in particular, but tactility is very good, providing clearly separated steps and controlled scrolling. The encoder comes from F-Switch (yellow, green core) and has a height of 13 mm. The middle (scroll wheel) click requires medium to high force for actuation. An elevated Huano switch (green plunger) is used here.

Surface

The Model I 2 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 Model I 2 Wireless is reasonably easy. First, all skates as well as the screws beneath them need to be removed. The top and bottom shell are readily separated now, but some caution is advised to prevent ripping any cables.

The internal design is reasonably efficient. The top and side buttons sit on their own PCB screwed into the top shell and connected through a ribbon cable with the main PCB, along with the battery. The left and right-side LED strips are likewise connected through ribbon cables. Everything else sits on the relatively spacious main PCB, which has been affixed to the bottom with three screws. The MCU is a PixArt PAR2862QN. The production date of the main PCB is the 45th week of 2022, whereas the side-button PCB has been manufactured during the 21st week of 2023.


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