I totally love this product. When I first got the sink installed, I wanted to keep it scratch free and the customer service guy at the store suggested this product. Though I felt it was a little pricey at that point, I cannot stop talking about the good it has done to my sink. It has been 7 years since and the sink still looks brand new. I would recommend this product to one and all. 

I got the white powder coated one previously and when I kept hot pots right on it, the top coating got burnt and eventually the iron inside the rack started rusting. So this time, I made sure I have to buy stainless steel so that heat would not hurt it. I am hoping that this is more permanent than the white one and may not need to replace it for another 10 years minimum.
