I have not installed the three toilets that I purchased (not your problem, but we ran into shoddy plumbing). However the three items seem to be of good quality.  I was skeptical at first thinking at the price paid that I would receive items of inferior quality. So I was pleasantly surprised when they arrived. The delivery person was professional and polite. Anyway, the experience from ordering to delivery was top-notch. Keep up the good work. RAV
