I bought these pans after a thorough search for the best product for the least price. These came with good recommendations and I have not been disappointed. I have had them for several months now and they preform beautifully. I do have to remind my husband to always cook on low because they heat up so efficiently.  But they cook well and clean up nicely. They do tarnish as all copper does. I keep a small tub of copper cleaner beside my sink and every few washings I give them a quick rub and there as good as new. I great investment. Hope to use them for years to come.
