I bought my Chi on ebay about 3 years ago for super cheap, I think $60 or so... it works beautifully! I have never had an iron that let me get such great results with minimal time and effort like the Chi does! Love it paired with the Silk Infusion drops too !
The price is worth it! My hairdresser talked me into spending the money for one because I was having to buy a new one every other month of the cheap ones and they just dried my hair out. The CHI does not dry my hair out, works fast, and my hair looks so much better with it. 2 years and it is still going strong! I would have spent a whole lot of more money on buying the cheap ones.
