It's completely silent, until you play music, the switch is only for muting/sleep, and there are no popping sounds, even removing and inserting the power cord, the only issue is that you will fry the chip if you give it the wrong polarity, don't ask me how I know this.
But on the whole it's pretty well perfect, for that price.

That should be requirement and not a bonus, doesn't it?

Well, that's quite unfortunate. To make it reverse polarity safe is not very difficult though. Fuse in series, 'reverse' polarity diode to gnd. Extremely simple, effective, no drop in voltage and if it's connected reverse the fuse blows.

Is the lid vented to let the heat out ?

I haven't tried to run a party with it yet, so I don't know how hot it would get. But I doubt there will ever be a problem, unless you get to an occasion where you should have something beefier in the first place, like all of these things, power is dictated by supply, and at 24V, you can expect a nice 20W at 8ohm, and that's a lot.

Most TDA7498 amps work well to excellent, easy to realze amp comcept. But, well, that amp got the same problem, if you use high power, the heat can't be dissipated - no air movement and exchange happens at all. Probably not a problem at neighbour-friendly levels but still an issue to look out for if you are throwing a party or got some low efficiency speakers like it becomes more and more popular.
