I installed this three days ago. So far, so good. Installation was slightly more complicated than a normal toilet, due to the design. But it wasn’t that bad. I’m very happy with the design and the two button flush. My only complaint is the size of the circle covers on each side of the toilet. I have seen other toilets with much smaller openings, but I know they are more difficult to install. If your toilet is between a wall or vanity, they may not be very noticeable. It’s a small gripe when you consider how easy this toilet base is to clean.
I am very happy with my purchase and will update if there are any problems in the future.
Update. I have been using this toilet for over a month now. I decreased the number of stars I originally gave it. This is NOT a power flush toilet, so you need to keep a toilet brush nearby. It never claimed to be a power flush toilet and I didn’t think that was a big deal, but now I do. Just an FYI.￼￼
