      I have been using this sink for a month now and am very happy. The different levels in the sink allow me to have the bin up high, so I don't have to bend down - this despite the sink itself being deeper than my previous two-basin sink. The included shelves and wash bin make it easy to do a variety of things - to strain pasta, I use my own colander and put that on one of the shelves (unlike in the past, trying to balance it on the divider between the two bowls of my previous sink). I can put a dirty pot on the bottom of the sink, and still have a washbasin at the top for the items I need to deal with right then and there. So far I have not had any rust issues. Remembering to when I ordered it a half a year ago, the sink came quickly and was well packaged. Overall, I am very happy. One point that for me is not an issue - We have it as an undermount under a quarz counter, and the counter person had to make the corners on the quartz counter to be not as sharp as they are on the sink. It does not create any problems.

      My wife fell in love with this sink after seeing it at a kitchen supply specialty store and had to have it for our kitchen remodel. She absolutely loves it! The great size and depth are perfect and she loves all the accessories and "work space" that they provide. We found that it actually keeps our kitchen much cleaner by working over the sink for many of the tasks that we would be doing on the counter top.

      I have wanted this sink for ages! I never dreamed I would find such a steal of a price as I found on Overstock!!!! This sink is amazing!!!!! I love all the accessories that came with it! One note: it doesn’t include the drain piece so you’ll need to purchase one for it.

      I'm thrilled with my new sink. It is truly a workhorse. Don't be fooled into thinking there are similar sinks out there for a lot less money; in all my research this is the only one with THREE levels for accessories, and that makes all the difference because it means there is room for all the accessory pieces to stay conveniently in the sink. This sink is the absolute favorite piece in my complete kitchen reno, and I'm so happy with my purchase.

      I used this sink at a friend's house and fell in love with it. When I started my kitchen remodel, I knew I had to have this sink. The add ins of the cutting board, soaking tray, colander, are fantastic. And the Overstock.com price was the best around.
