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.

This sink is very nice. It's great looking and I'm sure it will last as long as my old sink. Maybe even longer

This product was delivered in a very timely manner. It was shipped with no damages. And it has built a very good quality. This is a heavy sink. It looks very very nice. Very high-end sink for a very good price.

The only down side is typical for all under mounting units in that is very deep in the cabinet, leaves short space under or beside the drains for water distribution valves, led drivers, storage items and waste bins. I got it All in but it took careful space planning and sequencing of installations to get it all to fit in a 36” wide cabinet.

Me encantó la calidad del fregadero,esta super pesado, excelente calidad, llego en perfectas condiciones, solo compre los adaptadores de 1/2 a 3/8 como lo leí en una reseña y me funcionó, aunque debo decir que no es barato pero vale la pena

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

This was an as is but it said the box was only dented and torn. But once we took the sink out of the box we found 4 cracks we were able to repair with flex seel. Be sure to really ask questions about something before buying

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.

Very nice product with easy install on our new granite counters. Color is perfect if you have black or dark counters. Cleans up easy and love the strainer basket in the drain!
