Query: T3 Tourmaline Professional Featherweight Ceramic Ionic Hair Dryer

BUYER BEWARE !!!Be sure to purchase this dryer from the AUTHORIZED DEALER ONLY. This product might be a bit more expensive however it will save you hours of headaches and many dollars if you need to return the dryer within what you THINK is the warrentee period. Only the authorized dealer will stand by the 48 month warrentee. The dryer I purchased from Amazon broke before one year of use , it was NOT from an AUTHORIZED DEALER. I had a extremely hard time getting it replacemented. I was shuffeled back and forth between Amazon and the seller that provided Amazon the dryer; Glamor Beauty . After many heated hours on the phone with both parties, Amazon did send me what I think is a new dryer. It is not from an authorized dealer so I'm not sure how long this one will last.
