Type of plastic used? ABS? Polycarb?
What are those things on the side? Additional/optional USB-C ports to plug into instead of the rear?
Can we get pics of the feet/booty?
I have an FLEsports F12 Polia Edition: while the board itself is a super basic tray-mount design with ABS plastic it's solid and works well, so I have every reason to suspect this will also be solid. Also seems to have plate foam just like the F12, a nice add for this price point.
They're plate mounted. The PCB that came with mine also could accommodate screw-on stabilizers but I can't speak with confidence as to whether future production down the line might change this
