Build Quality

Overall build quality is solid. When shaking the mouse, a minor rattle comes from the main buttons. When applying lateral pressure, major creaking and minor flexing of the shell can be observed. Activating the side buttons by squeezing the sides is impossible. Lastly, if "Enable Button Optimization" within iCUE is set to off, no accidental clicks occur when slamming down the mouse, but if set to on (default), so-called slam clicking is very easy to reproduce.

Buttons

Main buttons on the Sabre RGB Pro are very good (left button) to good (right button). As they are spring-loaded, the clicks are very snappy, and both pre and post-travel are low. On the other hand, the right button in particular suffers from a mushy and dull response, and both buttons can be made to move slightly under one's fingers. While the buttons are visually separated from the shell, lateral button movement is low. Button stiffness is light. A pair of Omron D2FC-F-K (50 M) (China) switches is used.


Side buttons are bordering on excellent. Both pre and post-travel are low, and button response is pleasant and snappy. The pressure point is even across the buttons, too, although there is a slight hint of mushiness. Button placement is good as actuation is possible quite easily by rolling one's thumb across. A set of TTC switches (blue plunger) is used for these.

At the top of the mouse is a button for cycling through the set CPI levels. Its click feel is decent. Another TTC switch (red plunger) is used for this one.

Scroll Wheel

The scroll wheel is good. It's noisy when scrolling in either direction, but the individual steps are fairly well separated, resulting in good tactility. The encoder comes from TTC. Actuating the middle (scroll wheel) click requires very high force. A seemingly unbranded tactile switch is used here.

Coating

The Sabre RGB Pro has a slightly rougher matte surface all over. It doesn't attract fingerprints, dirt, or the likes 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 Sabre RGB Pro is fairly difficult. First, remove the two rear skates. Note that these are double-layered, so getting them off can prove tricky. With those taken care of, prying the mouse open at the back is the next step. Bottom and top shell are shut incredibly tight and clipped in at the front, so separating the two requires quite a bit of force. Eventually, it'll snap apart, hopefully without breaking anything in the process.

The internal design is pretty straightforward. The side buttons sit on their own PCB clipped in vertically and connected to the main PCB with a ribbon cable. An auxiliary PCB sits next to the scroll wheel, providing illumination. The main PCB holds everything else and is kept in place by no less than five screws. All PCBs are of moderate thickness. Production date for most of the PCBs is the 35th week of 2020. The MCU is an NXP LPC54605J512, whose datasheet can be found here.


As for the soldering and general quality of the PCBs, I'm unable to find any noteworthy flaws. In fact, I couldn't help but notice the impeccable solder job.
