Usually “everything is so cheap, right down to the seats!” should be cause for concern, at least when it comes to aviation. Just so long as they aren’t skimping on scheduled inspections, mechanics, parts etc.
“Fast, good, or cheap. Pick two.”
It seems they are making them cheap in the ways they can. I was almost too impressed with the seats on those things They must weigh less than a third of the weight of most airplane coach seats.
