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, no accidental clicks occur when slamming down the mouse.

Buttons

Main buttons on the DeathAdder V2 Mini are very good. Pre-travel is low and post-travel moderate, resulting in a firm button response. The right click sounds and feels a bit different than the right one, but unlike on the DeathAdder V2 Pro, there is no added mushiness, and actuation force is uniform between left and right. Button stiffness is medium to light. Razer-branded optical switches are used here.


Side buttons are very good. Pre-travel is low and post-travel moderate, resulting in a snappy button response. The pressure point is mostly even across the entirety of these, but the forward button in particular feels a bit flimsy as when pressed, the upper part retracts further into the shell than the bottom part. Button placement is great as actuation is possible very easily by rolling one's thumb across. A pair of TTC switches (white plunger) is used.

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.

Scroll Wheel

The scroll wheel is good. Scrolling is rather noisy, and the individual steps have decent separation, but scrolling feels a bit flimsy and "cheap," for lack of a better term. The encoder comes from TTC and has a height of 12 mm. The middle (scroll wheel) click requires medium to high force for actuation. Another tactile switch from TTC is used here.

Coating

The DeathAdder V2 Mini has a smooth matte surface at the top and rougher texture on the sides. Grip is fine on either. They don't attract fingerprints, dirt, or the likes too much, are easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.

Disassembly

Disassembling the DeathAdder V2 Mini is easy. The screws are located beneath the two skates at the front and the big one at the back. After those are taken care of, top and bottom shell can be separated. Two clips at the sides hold them together, so lifting off the front first and then applying force is the best approach. The internal design is simple. Everything sits on the fairly thin main PCB, including the vertically mounted side buttons. Three screws in total are used to affix the PCB to the bottom. The MCU is an NXP LPC11U35, which is used on the Viper Mini as well, and whose datasheet can be found here.


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