I have had one of these pans for about a year now. It gets quite a bit of use, probably about 2 times/week. It is definitely nonstick, I have not had a problem with that. It is heavy and seemed to be quite sturdy when I first started using it. However, after about 6 months, it started to get a bit warped. I've never had a problem with it while it's in the oven, it seems every time I take it out of the oven it snaps up into a warped position as the pan cools. Once I wash it, it seems to go back to normal though which I find somewhat odd. Also, I always pre-rinse things before putting them in the dishwasher...I never have problems with keeping pans clean until this one. It has developed a somewhat sticky beaded patch down in the corner of the pan. Not sure if this is the nonstick coating starting to wear or what, but it is another "minus" for the bakeware.

Overall, it's not a bad pan, especially at the Amazon price. But I definitely won't be running out for a second one.

DON'T BUY THESE BAKING SHEETS. I PLACED ONE IN A 425 OVEN AND IT WARPED, CAUSING A SPILL AND MESS IN THE OVEN.
