Good toilet, the one piece makes assembly easy if it were not for connecting to rusted bolts and a leaky valve.  Of course the big value points are low water usage, one piece, and compact which in bathroom was key, especially getting the oval seat vs round one without an extra 3+ inches.   Remember no wax ring or mounting bolts so you need to buy these at a hardware store.   For a low water usage toilet it does far better than the 50yr old 4 gal toilet.   Seat looks "cheap" , my wife's comments but actually looks I think are deceiving and I don't see any concerns. Definitely recommend
