Product review (5 stars): Love them so far.
These came very quickly and I like the way they look. I was worried that they might stayed curled up, but they laid flat in the oven.  I really like the fact you can put these on the bottom of the oven; so many of the competitive products need to be used on the bottom rack.  I haven't had the product long enough to determine the ease of cleaning, but so far, so good.
