I'm underwhelmed by this. The quality of the components and mechanical parts seems below average. The seat attachment works about 85% - i can't get it to tighten down and stay square on the bowl. The float and water inlet are the same as a house brand toilet from a big box store i got a couple months ago. Also it leaked a tiny bit at the water inlet and i had to re-install it. also all of the square, modern toilets are not comfortable to sit on.
