Build Quality

Overall build quality is solid. There is no rattle when shaking the mouse. When applying lateral pressure, major creaking but no flexing of the shell can be observed. Activating the side buttons by squeezing the sides is impossible. Lastly, accidental clicks when slamming down the mouse do not occur.

Buttons

Main buttons on the Slingshot are very good (left button) to good (right button). Both buttons have some pre-travel, along with significant post-travel. The right button feels as if it doesn't properly bottom out, resulting in a muted and harsh button response. On the second sample I've received, this is not the case, although button response still is more muted compared to the left button. Button stiffness is medium. A pair of unspecified Kailh switches with a red plunger and rated for 20 million clicks is used.


Side buttons are good. Post-travel is minimal on both, but pre-travel is significant, and the pressure point is far from even across the entirety of these. On the second sample I've received, pre-travel is improved on the forward button, but persists on the back button. Button size and placement are good, as actuation is possible rather easily by rolling one's thumb across. A set of TTC switches (white plunger) is used here.

At the top of the mouse is a single button for cycling through the set CPI steps, which feels fine. Another one of the unspecified Kailh switches (red plunger) is used for this one.

Scroll Wheel

The scroll wheel is very good. Noise levels are under control, and tactility is quite good, with decently separated steps and controlled scrolling. The encoder comes from TTC (black) and has a height of 14 mm. The middle (scroll wheel) click requires very high force for actuation. An elevated switch from HCNHK (white plunger) is used for this one.

Surface

The Slingshot has a slightly textured 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 Slingshot is easy. After all the skates and the screws beneath have been removed, top and bottom shell can be separated with ease.

The internal design is equally simple. The side buttons are vertically mounted atop an unnecessarily large plastic assembly. Everything else sits on the likewise needlessly large and moderately thick main PCB, aside from a single LED illuminating the scroll wheel located on an auxiliary PCB. No less than five screws are used to affix the PCB to the bottom, which once again may be deemed excessive. The MCU is a Sonix SN32F264, whose datasheet can be found here. Production date for the main PCB is the 27th week of 2022.


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