Hands down, these are the BEST pans I've ever cooked with! I have the Nanobond series; they heat nicely, cook evenly and cleanup is a breeze!!! They're light enough to handle easily but stand up to any type of utensil. And it's easy to keep them looking brand new; just use a little polish that comes with the pans and PRESTO! Definitely worth every penny! The only caveat is that you need to use grease (butter, oil, etc) no matter what you're cooking and let the pan heat up before cooking. This will keep anything from sticking, especially if you're used to cooking with only non-stick pans. Not only do I recommend these pans, but I would buy them again in a heartbeat!
