awesome sink
Absolutely love this sink. Great look, large & deep. Edges are so flush to the counter top. Bought the rack that goes on the bottom which just compliment the sink so well. Everyone who see the sink also loves it. Bought all new stainless appliances & this sink makes the kitchen just look awesome.Only draw back was that I have a stone countertop & it had to be widened to fit the sink because of the brackets that are welded to the underside of the sink.

beautiful sink, great replacement option
We bought this sink to replace a self-rimming sink. While we'd prefer an undermounted sink, we couldn't do it with our current granite. After having the existing hole (in the granite) modified a bit after removing the self-rimming sink, we installed this one. What a difference! It adds such a clean, modern feel to the kitchen, and oh! the space! To top it off, the sink is insulated so it doesn't "ding" when you drop a utensil in it.
Installation was a bit more complicated, as described by a previous reviewer, and it took a bit longer. But it's definitely doable if you plan for it.

Great sink
This is a really classy sink. Well built, strong, and BIG. I installed a 29" tall commercial grade pre-rinse faucet with it and it looks fantastic.

Great Sink
High quality product. Gooooo glad I chose it. Nice and deep and cooks dream. Since it could be installed either undermount of rimmed, we had the option for the way it was installed. We chose undermount. Came very quickly and had to wait til my granite was in. Would definately do business with Faucet Direct.com again.

Good sink, but things you should know
The look of the sink is very nice. Big, square, nice polished-steel. I would have given it a 5 star rating if it wasn't for two things:
1) There is a steel bar/bracket that runs along the underside edge of all 4 sides. This is NOT advertised in any of the literature here or from the manufacturer. If you are undermounting, then you can disregard. If you are self-rimming, this is important. The bar is used to attach the 10 supplied mouting brackets. Only the cutout guide (included with the product) shows you the cutout dimenions needed. The bars run about 3/8" in from the edge on all sides. Therefore your countertop cutout will need to account for this, or will have to be widened.
2) The edges are not 100% flat on plane. Mine arrived with a slight wavy curvature when looking straight across from the edges. You will not notice from above, but if you install it self-rimming you will notice small gaps between the edge of the sink and countertop. The metal is not that thick and bends relatively easily, so you can straighten it out (especially at the corners) if you are a perfectionist and this bothers you.
Other than that, I am happy with the sink. It looks very modern.

Fabulous!
The sink is wonderful - large and easy to clean. I'm looking forward to Thanksgiving and washing up the roaster in one deep sink. I am very satisfied and would be happy to recommend this product and this website to anyone.
