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, accidental clicks do not occur when slamming down the mouse, irrespective of what the debounce time is set to.

Buttons

Main buttons on the Atlantis are very good. Pre-travel is moderate, but post-travel fairly low, resulting in a fairly firm and snappy button response. While the buttons are visually separated from the shell, lateral button movement is minimal and needs to be provoked. Button stiffness is medium. A pair of Huano switches (blue shell, pink plunger) is used for these.


Side buttons are very good. Pre-travel is very low, but the buttons can be pushed quite a bit past their actuation point, resulting in a snappy and pleasing button response nonetheless. The pressure point is even across the entirety of these. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of Kailh switches (red plunger) is used here. I have been informed by LAMZU that from the second batch onward, Huano switches will be used instead.

At the bottom of the mouse is a single button for cycling through the set CPI levels, which works just fine. A seemingly unbranded tactile switch is used for this one. The slider at the bottom switches between on and off-state. While fairly stiff, this slider also works just fine.

Scroll Wheel

The scroll wheel is good. Noise levels are elevated, but tactility is quite good, providing clearly separated steps and controlled scrolling. The encoder comes from TTC (yellow) and has a height of 9 mm. The middle (scroll wheel) click requires high force for actuation. A switch from YSA (red plunger) is used for this one.

Surface

The Atlantis has a smooth matte surface all over. Grip is fine, and it doesn't attract fingerprints or dirt 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 Atlantis is easy. The screws are located beneath the front and rear skates. The sides are additionally locked in with clips, which are fairly easy to dislodge.

The design differs from most others. The side buttons sit on a rather large PCB elevated above the main PCB, accompanied by the battery and connected to the main PCB through a ribbon cable. All PCBs are very thin and have larger cutouts and holes to save additional weight. Simply making the PCBs smaller in the first place would have been a more sensible approach, although the side-button PCB at least serves a purpose in ensuring structural integrity. Three screws are used for the former and an additional four screws for the main PCB. The MCU is a CompX CX52850. Production date for the main PCB is the 31st week of 2022.


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