Build Quality

Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, minor creaking but no flexing of the shell can be observed. Activating the side buttons by squeezing the sides requires high but not excessive force. Lastly, no accidental clicks occur when slamming down the mouse.

Buttons

Main buttons on the Orochi V2 are very good. Pre-travel is moderate and post-travel low, resulting in a firm and fairly snappy button response with good uniformity between the left and right buttons. Button stiffness is medium. Though described as second-generation Razer mechanical switches, these are in fact modified Kailh GM 4.0 (60 M).


Side buttons are very good. Pre-travel is low, but post-travel moderate (forward) to high (back button), resulting in a satisfying button response nonetheless. The pressure point is mostly even across the entirety of these. Button placement is great as actuation is possible very easily by rolling one's thumb across. A set of TTC switches (white plunger) is used here.

At the top of the mouse is a single button for cycling through the set CPI steps, which works just fine. A tactile switch from TTC is used for this one. A slider at the bottom switches between 2.4 GHz, Bluetooth, and off-state, which too works fine.

Scroll Wheel

The scroll wheel is very good. Scrolling is a bit noisy, but tactility is on point, with clearly discernible steps and a matching tactile feel when scrolling. The encoder comes from TTC and has a height of 9 mm. The middle (scroll wheel) click requires medium force for actuation. Another tactile switch from TTC is used here.

Coating

The Orochi V2 has a slightly rougher matte surface all over, which provides great grip. It doesn't attract fingerprints, dirt, or the likes too much, is easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.

Whereas the top cover of the regular Orochi V2 is made out of ABS, a polycarbonate is used for custom top covers available through Razer, which also have a smoother texture.

Disassembly

Disassembling the Orochi V2 is virtually trivial. After taking off the top cover, the four TORX T6 screws are readily exposed and only need to be removed, which allows for pulling off the top shell. The internal design is equally simple. Everything sits on the thin main PCB, aside from the side and top buttons, which have their own slightly thicker PCB screwed into the top shell and connected through a 10-pin connector. The battery holder connects through that PCB as well. Three screws in total are used to affix the PCB to the bottom. The MCU is a Nordic nRF52840, whose datasheet can be found here. Production date for the side-button PCB is the third week of 2021.

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