Product review (3 stars): Not completely happy.
1) After having this installed for less than 6 months, the Oil Rubbed Bronze finish is wearing off round the inside edges.  The entire point of paying the very high price for this product is so that the finish matches faucets and other items in the kitchen, so having the finish wear off pretty much kills the value of the item.

2) The instructions tell you not to use Plumbers Putty, without explaining why.  This is confusing, since Plumbers Putty is what it traditionally used to install these.

3) There are about 6 different finishes that are described as Oil Rubbed Bronze, and although they are close in color, you'll notice the difference if you don't have an exact match.  This ORB flange looked different from the traditional ORB sink strainer on the other bowl of my double sink, and different from the ORB faucet assembly.

Oil Rubbed Bronze specialty items are hard to find, even here in one of America's larger cities, and that's why I ended up buying this on line.  It would have been better if I could buy it locally.
