Build Quality

Overall build quality is mostly solid. There is a very slight rattle when shaking the mouse. When applying lateral pressure, minor creaking of the shell can be observed. It is possible to activate the side buttons by squeezing the sides with moderate force. Lastly, no accidental clicks occur when slamming the mouse down.

Buttons

Main buttons on the Cobra M711 FPS are very good. Pre-travel is low and post-travel is very low, which results in a firm and satisfying click feel. Button stiffness is light. LK optical switches (white plunger) are used here.


Side buttons are good. The forward button is rather noisy, depending on where it's pressed. Both pre and post-travel are pretty low, though. However, the pressure point isn't even, resulting in a somewhat flimsy and mushy click feel. Button size and placement are good as actuation is possible rather easily by rolling one's thumb over these. CF switches (red plunger) are used for these.

At the top of the mouse are two buttons for cycling up and down through the set CPI levels and a button for cycling through the lighting modes. Their click feel is decent. Huano switches (red plunger) are used here. At the bottom of the mouse is a dedicated button for switching through on-board profiles.

Scroll Wheel

The scroll wheel is very good. Neither scrolling up or down produces any unwanted noise. The individual steps lack separation though, which results in poor tactility. The Encoder is a pink F-Switch. The middle scroll wheel click requires medium force for actuation. The switch used here looks like a counterfeit Omron.

Coating

The Cobra M711 FPS has a matte coating on top and non-coated textured ABS plastic on the sides. It's quite grippy, but does attract fingerprints, dirt, or the likes quite a bit. Some signs of wear may still be visible even after cleaning. All in all, a good coating.

Disassembly

Disassembling the Cobra M711 FPS is easy. Just remove the two mouse feet, unscrew the screws (five in total), and pop the top and bottom shell apart. The internal design is pretty straightforward as well. The top shell consists of two layers, one of which is translucent. Everything sits on a single PCB except for the side and top buttons, which have their own PCB screwed into the top shell and connected to the main PCB through a 6-pin JST connector. Additionally, a small elevated PCB is attached to the scroll wheel for illumination. LEDs are placed all around the PCB for illumination. All PCBs are of moderate thickness. Production for the PCB is the 45th week of 2019, while the design date is much earlier (2015 and 2017, respectively). The screwed in internal weight also acts as stabilization for the main PCB, which is affixed to the bottom shell only by the screw securing the elevated scroll wheel PCB and two pins otherwise. The MCU is a Holtek HT68FB560, the datasheet of which can be found here.


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