Query: Buyer Beware

I ordered this item for my daughter in late February. For 5 months it worked well until just a few days ago when it would no longer turn on. I phoned Farouk Systems to inquire about this problem. They told me that Amazon is not an authorized seller of their products, thus are not covered by their warranty (they only warranty products sold through salons.) So, buyer beware.
