I have the Karlie Wonder wheel and it's fine. Fairly quiet, although I understand Alfred likes to unload his pouches into it, so bits go flying around quite noisily.

Yes you do have to treat it but that is really simple -even I can do it. We got a small bottle of clear paint-on Plasticoat from Amazon and painted it twice, allowing it to dry. I have sometimes wiped it out with a wet cloth, and no problem.

I have mine in a ZZ2, I just make the substrate less thick underneath it, so it fits. But be warned, no substrate means a lot of rattling!
