This sink is really cool. The quality of the sink was exactly as advertised and expected.  Although the sample photo is not the Anthracite color I specified, I was able to toggle the correct color selection while making the purchase, and the sink showed up Anthracite color. It did appear dark gray to black, and it is just that.  The composite granite is a very hard materiel and will definitely work well for many years.
Sink came in a well protected package incurring no damage (in fact I think they over-packed it) and it shipped really fast, even though it was not needed as quickly for my project.   You can count on the quality of the Blanco sink line, and Wayfair for doing a great job of selling it at a good price.
