My son bought the instyler for myself and his girlfriend. He ordered from the television gettting two for one offer. She has very straight hair and I have extremely curly hair. The instyler would not even begin to straighten my hair and it did not make a difference in hers at all. This is the absolute worst product that I have ever used. Not even one promise made on the funciton of the equipment was true. I would advise everyone to save their money and not buy this product. It is a true piece of junk and a complete disappointment!! read full review »
