We registered and received this set as well as the colassus pan as a wedding present in April. We bought a house with a glass top electric oven. Having our kitchen products be earth friendly is very important to me. Before use, I followed the directions and seasoned each pan. I have already had to re-season my pans at least three times and that is with using non-stick sprays when cooking. They claim to be top-rack safe, but even with handwashing 80% of the time, the non-stick coating is coming off (and no, we don't use metal utensils on it). The handles retain water somehow and leak out when I am cooking causing burning on my glass top. It's an okay first set but I am glad we didn't purchase this set for ourselves. We will be looking to invest in higher quality cookware very soon.
