First of all, I like the feel and the features

The pitch and modulation wheels have a really nice feel to them, as well as the volume slider

Speaking of velocity, despite the uh less responsive overall feel of the keyboard, once one's touch is adjusted to the needed firmer / more unpleasant level, at least the AKM320's velocity output doesn't seem arbitrary or wildly inconsistent; it seems about on par with my "big brand" controllers

I suspect this is because these keyboards obligatorily omitted velocity, and when you add that requirement to the equation you end up with keyboards that aren't as fun or as quick-feeling to play as an old thrift-store Casiotone; there's probably just not enough throw in the tiny keystrokes to allow for some semblance of satisfactory velocity response (which requires either a force-sensing resistor or multiple switches)
