This is a very nice seat.  It appears to be well made and sturdy.  It is a little heavier and the finish has a higher gloss than I was expecting.  It looks like it will last a lifetime or more.  Installation was very easy although the instructions did not explicitly address the tapered washers/spacers and how they were to be installed.  The lid stands up easily by going slightly overcenter.  The lid and seat are relatively heavy so be careful when lowering either or both.
