Totally love the sleekness, design, and functionality of this toilet. My only frustration with this toilet is the seat. For some reason the holes in the base of the toilet are not level and therefore when the seat is attached, it is not straight. We have figured out a way to make it work but wish the manufacturer could fix the problem so as to not cause the consumer the headache of figuring out. Again, though, LOVE the toilet. Flushes great every time, no matter what it's flushing, lol.
