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, and it's impossible to activate the side buttons by squeezing the sides. Lastly, no accidental clicks occur when slamming down the mouse.

Buttons

Main buttons on the first copy I tested are alright at most, but good on the second one. Pre-travel is low and post-travel moderate (more so on the right button), resulting in a fairly firm and satisfying click response. On the first copy, click feel is remarkably poor, with the right button being the greater offender, having a muffled and muted click that almost feels defective. Even disassembled, the difference between the right and left main button switch is palpable. The second copy is much better in this regard, and while these are not my favorite main button clicks of recent Razer releases with optical switches, they're decent enough. Second-generation Razer optical switches are used.


Side buttons are excellent. Both pre and post-travel are exceptionally low, and the pressure point is even across the entirety of these buttons. They are somewhat hard to press, though, which can be a good or bad thing. Button size and placement is great as well, as they can be actuated very easily by running one's thumb across. A set of TTC switches (white plunger) is used here.

At the top of the mouse are two buttons for cycling through the set CPI levels. Their click feel is good, and two small tactile switches are used for these. At the bottom of the mouse is a button that cycles through the profiles, along with a slider that switches between off-state, wireless, and Bluetooth, both of which work well.

Scroll Wheel

The scroll wheel is very good. Scrolling up is a bit noisy, but scrolling down isn't, and tactility is good, with clearly separated steps. Though not perfect, this is probably the best scroll wheel on a DeathAdder yet. The encoder comes from TTC. The middle (scroll wheel) click requires medium to low force for actuation. A seemingly unbranded tactile switch is used here.

Coating

While the top features a smooth, matte coating, the sides are injection-molded rubber. Both provide great grip and don't attract fingerprints, dirt, or the likes too much. The surfaces are easy to clean, and there are no signs of wear after doing so. All in all, excellent materials.

Disassembly

Disassembling the DeathAdder V2 Pro is not necessarily difficult, but quite iffy. First, remove all three mouse skates. Beneath are Torx T6 screws, so you had better have a suitable screwdriver ready. After getting rid of those, the top and bottom shells will still refuse to come off. I'm not sure whether there is a "smart" way to separate these, but I simply ran out of ideas and brute-forced my way in by hooking a piece of metal into the dongle compartment and pulling the entire bottom out. Definitely far from elegant, but aside from unplugging the side-button PCB, nothing bad happened.

The internal design is somewhat complex. As mentioned, the side and CPI buttons sit on their own PCB screwed into the top shell and connected to the main PCB through a 5-pin JST connector. The battery is mounted atop the main PCB, covering part of the sensor and an IC. The main PCB is quite large and thin, and no less than five screws are used to affix it and the battery to the bottom shell. On the other side of the PCB, the MCU and an additional IC are found. The MCU is a Nordic nRF52840, whose datasheet can be found here. Finally, an auxiliary PCB below the main PCB has the micro-USB connector. Production date for the main PCB is the 20th week of 2020, whereas the side-button PCB was manufactured during the 21st week of 2020.


As for the soldering and general quality of the PCB, some of the solder joints on the backside of the main PCB leave room for improvement.
