Rated 3.5 out of 5 by 24 reviewers.
Rated 1.0 out of 5.0 by Keep Your Receipt I was so excited when I first got this sink. I babied it. I followed the cleaning instructions in the manual. Within 6 months it started getting these tiny cracks that you couldn't feel but stayed stained. Now the bottom of my sink looks horrendous. I have the desert sand color. I really wish I could find my receipt, and believe me I have looked. I called Mont Blanc, but they are clearly not even interested in talking to anyone without a receipt. I even offered to send pictures. The sink is barely 3 years old and it looks 40 years old. My previous home had a 50 year old enameled cast iron sink that looked better than this piece of garbage. I understand companies want proof of purchase, but when your product hasn't been around that long and held up so poorly, one would think they would be concerned with their product's reputation. I don't know if they have quality control issues, or if the problem was unique to my color. I'm so disappointed since this sink originally looked so good in my redone kitchen. Buyer beware. I'm going back to stainless steel. February 25, 2015
Rated 5.0 out of 5.0 by Great Product! I had this sink installed 2 months ago to replace a stainless steel one, hoping it wouldn't show water stains and buildup like that one - and it doesn't. I love the material: it's easy to clean but durable at the same time, you don't have to worry about accidently dropping things and marks come off easily with the soft soap-type cleanser. I also had an oil-rubbed bronze faucet set installed, looks great with the sink. Good value for the price! May 19, 2014
Rated 1.0 out of 5.0 by very disappointed. Got off white granite. It stains from everything! Coffee, juice, tea,. Stains from every single use. Chips, scratches. It was such a disappointment. Looked great new. Cannot get the stains out with anything I try. Will replace it with stainless. July 12, 2015
Rated 5.0 out of 5.0 by A great product The sink was very easy to install and looks great in our new kitchen, Thank you Home Depot for the great product. February 12, 2014
Rated 5.0 out of 5.0 by Great depth The depth of this sink enables one to wash dishes without water spattering all over the countertop. August 4, 2015
Rated 1.0 out of 5.0 by Horrible Waranty Bought this sink for to be under-mounted on quartz countertop. Six month later the sink cracked The only way to get any warranty satisfaction is to bring the sink back and they will replace. The sink has to have plumbing disconnected and reconnected. The top has to be lifted for the sink to be removed. None of that is covered. Just the $149. February 23, 2015
Rated 1.0 out of 5.0 by Do Not Buy this Sink Installing the sink was very easy. It is light and was easy to line up . Look nice and deep bowls. I replaced an old sink. After 10 days I have noticed cracks on the bottom of both bowls. Purchased on 5/27/2015 in Mchenry il . I wish I have seen the reviews before I purchased it. I have called the makers help line 770-924-6391 and always get some voicemail. I have to remove the sink now. Not the hardest job , but should not have to. Very unhappy with this product June 7, 2015
Rated 1.0 out of 5.0 by Terrible product Had a composite sink in our old home, loved it. Bought this one (different manufacturer) and have had it just over one year. We have followed all manufacturer's instructions, but the sink is stained, and looks at least twenty years old! It will not clean, and has yellowed and just looks dirty. We are going to replace it, and will never buy this brand again. :( January 3, 2014
