Glad to see some customers are not running into defects. For me, American Standard got it wrong, Home Depot made it right.
By the way, it does flush OK after Home Depot and I fixed the multiple quality problems:
1) Had to hold lever down until water makes loud gurgle in bowl, then release (else no flush); there was a styrofoam float missing from top of flapper.
2) Leak from tank bolt or tank outlet. Found this helpful comment above: "As far as I can tell, it's leaking around the sides of the gasket that goes between the tank and the bowl. If I fill the tank and watch that space, I see water starting to well up there, and then eventually start dripping out through the bolt holes... Yes, that's your leak. The large plastic nut may need to be tightened..." There was a gap between the large plastic nut and the rough porcelain surface.
3) Instructions do NOT correspond to parts, for example, no mention of the extra(?) pair of tight-fitting plastic 'washers' - maybe useful to clip the bowl base bolts into place and stop them wandering while lifting the heavy bowl into place (not mentioned in instructions).
4) It's a tough job to cut bolts after bowl is installed, so that bolt covers fit properly. Instructions should give an alternative of measuring *very carefully*, put on a nut temporarily, cut off amount indicated by measurement, then re-thread with nut. Use hacksaw or Dremel with cutter blade?
Tank went back to Home Depot, they exchanged the tank. (If they had to order replacement, I would suggest they order at least 2, so there is a better chance of one being defect-free). There is now a softer gasket, perhaps a design change to fix leak problems. I'm wary of American Standard, there seem to be quality problems. Would give it 2/5 since it does flush OK once the leaks and defects are fixed; includes a handy long nut driver for tightening nuts on tank bolts. Acts like a dual flush now: poke handle and it flushes using part of tank (about 3 liters), hold handle down and it empties tank (about 5 liters).
