I am not familiar with this model either, but American Standard toilets have a very high return due to manufacturing defects. If you go for any AS, take it out of the box and inspect it very carefully. Make certain it sets level and in full contact with the floor. Look for patched holes or other blemishes. This may be a builder grade which is a cheap model that builders buy to install in their spec houses so they can keep the home priced as low as possible and their profit margin up. These toilets are frequently replaced by the homeowners shortly after the sale. Most of us on this forum prefer the Toto line. Round fronts are not very popular now days, but there are some.
