I have had my Calphalon pots and pans for over a year now and have really enjoyed them. I love the hard adonized surface and have had no problems at all with them. I use silicone utensils on them and they have gotten no scratches. I like the pots, but do have a complaint about the lids. When I have something on the stove and take the lid off (like for pasta), the lid travels around on my glasstop surface. It's like there is pressure underneath it or something and it slides all around. I've never had a lid fall off, but if you don't have some kind of raised edge then I can see that happening. So maybe turn the lids with the handle side down and that shouldn't happen. But overall I really love these pots and pans. Design Another thing about the design I have found is that with the steamer insert the handles get very hot. So just be careful of that not to burn yourself. And then the other thing abuot the design would be that the lids move around by themselves on my glass top stove after the water has boiled and I have taken the lid off.
