They finished setting up at our wedding about 45 minutes later than the scheduled start time. They tried to claim they were less than 15 minutes late and refused to acknowledge their booth's own timestamped photos of their own operator tweaking settings more than half an hour after the start time.

I expected the management to take more of an interest and not ignore photographic evidence backing up my complaint.

A net score of 2 stars though because if you get an operator who sets it up on time and doesn't spend most of the evening playing on his phone and looking bored at your wedding, then the product itself can inject some fun into your event. Perhaps the best advice is to choose a professional operator close to your event.
