    Very durable and the grid prevent the surface from scratches. So it’s always shiny and nice.

    Price is right!
    Giving it four stars because it's not installed yet, so can't speak to the sound proofing, or spotting, etc., but it is beautiful, the price was far better than many sinks I had looked at, and when there was an issue with the first sink, Erin, Returns Manager, was quick to come up with a solution. I look forward to baking some cookies so I can submerge the entire cookie sheet into my beautiful deep and wide sink!

    Still remodeling have not installed yet
    I can't wait to get this sink installed. It is big, and looks great. It arrived in 2 days and is better then anything I saw in the big box stores. Plus I would have had a harder time finding the small size I needed. Great Price, Great Look, very Happy.

    Nice sink. I was a little disappointed with the sound dampening "pads" but haven't been bothered by excessive noise. The disposal drain that we installed does not fit the hole very well, and left a gap where the water puddles. I'm hoping it doesn't collect too much gunk over time. All in all I am happy with the sink. It's just the right size, and not too deep. Price was right for us!
