Soooo, I wanted a porcelain sink because I love the look and feel of a classic sink.  They clean up so nicely and they are heavy so that they are silent when you run the garbage disposal.  Unfortunately, I went with this sink instead.  I thought the square lines were cool and thought I'd give it a try.  Moral to the story is don't "give it a try" when it's something that is pretty much permanently installed.  It doesn't clean as well as porcelain and it isn't smooth like porcelain.  The biggest issue however is that it has developed a crack at one corner.  It's hairline right now and hopefully won't grow.  I sure hope that it doesn't get any more cracks or it's going to look really ratty really soon.  It wasn't cheap to have it installed and I sure hate the idea of having to replace it.  It's only been in the house for approximately 2 months.  Do yourself and favor and buy a porcelain sink.  You can't go wrong with them.
