Just received a Premium (production date Feb 17th 2020) yesterday. It was supposed to go straight onto location, but the bar is temporarily closed due to COVID-19, so it was delivered to my home office instead. Oh, the agony!
Quite satisfied with the state out of the box. I swapped the PSU fan for a more silent one, and put in a sheet of anti-glare playfield glass. The left ramp / TK lock shot is pretty evil and could perhaps do with some adjustment, but everything else seems good so far, including the demogorgon.
