Marble frying pan?

I plan to buy this marble frying pan that I saw in a TV home shopping channel where this pan would enables you to fry without cooking oil & the food won't stick to the pan in a better way than normal non-stick coating frying pan

I need experience from people who owns or have use it. I'm not a seller of this product, just prospective buyer who want 2nd opinion before settling as the items sold in a package & not that cheap also.
