Review: Quality - glad we bought it. - Looks nice, cleans up easy, doesn't chip, has a deep drain screener to catch debris, if you have hard water like we do, the spots easily come off easy with a spray calcium-lime remover. Quality item - glad we bought.
Review: Great sink...recommended! - Love this sink. It looks professional quality, is easy to clean, and the granite makes it stand out from all the stainless steel options that are out there. I like the sink depth, can wash a bunch of dishes at a tim. One word of caution — the granite is not forgiving to plates and glasses like stainless steel can be so be a little more cautious when washing

### ⭐⭐⭐⭐ I would say I am happy with the quality and the appearance
*by D***. on February 22, 2015*

We recently remodeled our kitchen with Bianco Antico granite which is a lighter colored stone with patches of dark grey/brown. We originally had a white enameled cast iron sink (with the old counter tops) and we wanted something really sharp and modern looking. Given a choice, I probably would have preferred a single large sink, but the wife overruled me and insisted on a 50/50 sink with two equal sized bowls. After shopping around a LOT, we finally settled on this unit. Overall, I would say I am happy with the quality and the appearance, but I think we could have done a little better. For one thing, the bottom of the bowls seems slightly small/narrow. I really wanted a nice, large sink that could easily accommodate large pots/pans for soaking, but this just doesn't quite cut it. Yes, I was aware of the dimensions before ordering, and on paper this sink seemed to be the right size, but installed it just feels a little smaller than I would have preferred. That really isn't a negative comment about the sink. I am sure it's exactly the size we ordered. I just wish that the actual dimensions were a little larger....and for what it's worth, I don't think many sinks would fit that criteria -- pretty much everything I looked at in the big box stores and online was a similar size....and most were actually smaller than this. So maybe I need to adjust my own expectations? Final thing -- this is my first "granite composite" sink. I like the concept, but I dunno -- it looks nice, but my guess is that 99% of people who look at the sink would guess that it's just solid plastic.....because that's how it looks. It does have a very thick, solid feel to it, but it still ends up looking a little like plastic. If I sound unhappy with the sink, I'm really not. Would I order another one? Probably -- unless I could find something that was clearly way better.
