I purchased the square Copper Chef pan almost a year ago after seeing commercials of what was supposedly a wonderful pan.
The first time I used it on the stove as I was stirring, I realized it was very awkward stirring in a round circular motion into a square pan because the corners we're not getting stirred, so you have to stir in a square motion which is not natural. Aside from that, everything seemed to be fine at first. But it is not "non-stick" as they claim to be.
Food did not just slide out of the pan as the commercial shows. However, at first, it was fairly easy to clean up. But after using it as a fryer, grease residue has stuck to the top half of the pan and will not come out. I have tried everything. The only way I was able to remove a little bit of the fried on grease or baked-on grease was to use the side of a butter knife, which appeared to start scratching the surface of the pan, so I stopped. The outside of the pan looks like I've had it for many many many years and it is not an attractive pan at all.
I called customer service twice and spoke to two different representatives with heavy accents which were hard to understand, but they also really didn't care what I did with the pan. The first call the man said he would send me an email with information to send it back and they would replace it. However, that leaves me without a pan for almost three weeks, and the shipping cost is almost $15 to send it, and that is at my expense since they do not refund the shipping. It will cost me money to have the pen replaced.
So the commercial is not true when they say that they will replace it absolutely free. I will also be posting my reviews on other websites that will allow me to post the pictures so people can actually see what this pan looks like after minimal use. I gave my review two stars, but after talking to customer service, I should have reduced it to a one-star.
Bottom Line: No, I would not recommend this to a friend
