Overall, this is a very durable, heavy, well designed and ideal double faucet sink. It is exactly what I am looking for with one exception. ..we are using it as a countertop sink, not a wall mount sink, and the back of our sink is bare porcelain. It is not porcelain coated which means it will be noticeable in the reflection of the mirror. 

The mounting holes and casting hole (3 total) were somewhat expected. We have already painted the back white, and are deciding if we have to clear-coat it before installing it (still undecided), but we might test it in place on the counter before making that decision. It delayed the install by a day or two for this/these changes. We are also deciding if we want to fill the mounting holes. So...what would have been a 5-star purchase loses a star.

I would buy it again, but also know my purchase will need work before I can use it as I intended.
