Build Quality
Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, loud creaking can be provoked when pressing a specific spot, but otherwise, there's neither creaking nor flexing. It's impossible to activate the side buttons by squeezing the sides. Lastly, no accidental clicks occur when slamming down the mouse.
Main buttons on the Xlite are very good. The left one has some post-travel, but pre-travel is uniformly low, resulting in a firm and snappy button response. Click feel is good too, although the shell imparts a certain degree of rigidity. Button stiffness is medium. A set of Omron D2FC-F-7N (20M) (OF) (China) switches is used.
Side buttons are very good. The forward button has some post-travel, but other than that, both pre and post-travel are low, and the pressure point is even across the entirety of these buttons. Button placement is good as actuation is possible very easily by rolling one's thumb across. A pair of MWK tactile switches is used for these.
The scroll wheel is very good. It can get noisy when scrolling fast, but tactility is good, with clearly separated steps and pleasant scrolling. The encoder comes from F-Switch. The middle (scroll wheel) click requires high force for actuation. A Huano switch (blue plunger) is used here.
Coating
The Xlite has a smooth matte surface. 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 Xlite is very easy. Remove the two rear skates and unscrew the screws beneath—top and bottom shells will now be separated easily. The internal design is pretty much as efficient as it gets. Doing without RGB and a dedicated CPI button allowed Pulsar to make do with a single PCB. The side buttons are mounted vertically atop the PCB, which is very thin to save as much weight as possible. Four screws are used to affix the PCB to the bottom shell. The MCU is a WTU301 N36C-C, which is found on the Xtrfy M4 and M42, among others.
As for the soldering and general quality of the PCB, I'm unable to find any noteworthy flaws.
