I don't know how the pan really works, but I had a negative experience with the company itself so my review is regarding this.
I went to their website and put this pan in my cart. It had me enter my credit card information, and then I clicked next, expecting it to go to a page where I could confirm my order. It went to offer after offer, trying to make me upgrade to more pans. Finally, I got sick of it and exited the page.
A few minutes later I got a confirmation saying that I had purchased not only the pan, but a "free" gift which I had to pay about $7 shipping for. I did not want that, and it never gave me the option to reject the gift so I called the company immediately and told the woman I wanted to cancel my order. She tried to get me to but the pan without the "free" gift, but I said no, so she told me she would put a note in to cancel it.
About a week later, the pan arrived in the mail, and I noticed that my card had been charged for the pan and "free" gift. I called the company to say that I had cancelled my order, and that this should have never been sent. I told them I did not want to pay the shipping to send it back because I, first of all, did not confirm to order it, and secondly, cancelled it immediately when I saw that it had gone through.
She told me that the computer says I cancelled it on April 5th, after it had been sent. This is not true, because I called 5 minutes after I received the receipt in my email on March 30th. She said sorry, there was nothing she could do, if I wanted I could send it back and get refunded for the price of the item but not the shipping.
I ended up filing a claim with my bank and giving the box back to the post office as a "Return to Sender," so that I wouldn't have to pay shipping. They ended up refunding the entire charge (which is why they get 2 stars instead of 1) but if I had not been so determined to not let them make me pay shipping, I could have easily paid $20 worth of shipping charges for something I didn't even commit to ordering.
P.S. I hate writing bad reviews. I only wrote this so that other people don't get scammed like I almost did.
