I purchased this sink mainly for the shape and price, then came back and read all the reviews and started second guessing my purchase. I've had the Vigo for close to 8 months now and am so happy with it! I came back to edit my previous review to provide more detail. 

As described, the sink is matte—it feels a little bit like Corian. It does not feel or look like plastic and does not look cheap. I was also a little concerned about the staining as it does show red wine or coffee quickly. I used powder sink cleaner (Ajax) as suggested and it cleans to perfectly white extremely easily—I just use our dish brush and very little scrubbing. 

We have a modern farmhouse kitchen (pictured) and the sink fits in perfectly—low profile, but really beautiful!
