Garbage, Garbage, Garbage from installation point  to quality of materials.
When my contractor installed it, two edges had gap between the sink and the counter top and we had to fill it with silicone. Definitely defective and very low quality product as other people mentioned in their reviews.
Worse than that, after one week started rusting as you see in the attached pictures. 
And after all, I noticed this sink is not Cantrio brand because I bought two and the other one has Catrio logo on the sink and it's made in China. 
Anyway, after a lot of challenges with Wayfair customer service, I was able to get a full refund for the sink.
I don't recommend this sink but definitely I recommend dealing with Wayfair
