Rated 4.8 out of 5 by 34 reviewers.
Rated 5.0 out of 5.0 by Exceeds expectations Beautiful deep sink. Easy to clean. It's white and so far no stains noted at all. No water marks noted. After cleaning an aluminum roasting pan some metal mark left by pan cleaned right up with dish washing detergent. September 17, 2013
Rated 5.0 out of 5.0 by Fantastic Finish -Durable and Attractive I was skeptical at first buying a white composite kitchen sink. Knowing how white sinks are in utility tubs and how they easily stain. Not this sink. I have washed the dishes each night sometimes poured coffee into it and cleaned spaghetti pots and not a glimmer of stain. Of course, you can't leave things sitting around for days but with due diligence it cleans up everyday. We love it! June 11, 2013
Rated 4.0 out of 5.0 by Beautiful sink! This sink is a vast improvement over our original stainless steel one! It is more than twice the depth and has a beautiful matte cream color. I was worried that a light colored sink would stain easily but we have had no problems. Even with the three big reds: beets, bbq sauce, and pasta suace. The only issue we had was that the instructions provided for installation were not very clear (small list provided in the corner of the cut out template) and appeared to be for a different sink model. Also, the instructions provided very little clarification on how the clamps were designed to work. With a little intuitive thinking we were able figure it out and get the sink installed.

Rated 5.0 out of 5.0 by Love this sink! I love this sink. It was installed 6 weeks ago and I've found no issue with it. Our countertop contractor installed it as an undermount as part of our new countertop installation, so I cannot comment on the ease of installation. Although it is a matte black finish, it has small sparkles in it which really look nice. It has a soft feel to it, not as hard as our previous ceramic sink. It almost feels as if a glass would not break in it, although I haven't had the chance to test this out yet! It does show some water spots on it when it dries, but I don't see this as an issue. I am constantly cooking and using the sink, so I don't expect it to be perfectly spotless at all times. Our neighbors had never seen a composite granite sink before and were impressed with its look and feel. The picture attached shows how it looks dry and wet, although the reflection in the pic takes away some of the beauty. It is much nicer looking than in the picture. December 27, 2012
Rated 5.0 out of 5.0 by LOVE IT! Love my new sink! It is very nice looking, cleans up very nice. Will be so nice not to have to use bleach to clean this like my old cast iron sink. February 11, 2014
