This sink was great for about 10months. Then we noticed a hairline crack that has now extended to outer rim.  I was so disappointed especially since we bought the metal sink grate for protection and I was very cautious with cleaning products.  The only thing I can think of us that we would pour hot pasta water in sink... but that seems like daily use.  Of course it has been 16 months now so wayfairs warranty has expired. I wish we would of used local company to buy this sink to assist us with this process.  We are currently contacting elkay for either touch up kit or replacement.  This product is too expensive to crack!
