Query: DO NOT BUY - NOT AN AUTHORIZED RETAILER

CHI and other Farouk Systems products are only sold through authorized salon retailers, and Amazon is not one of them. (This also includes CHI products sold at places like Target.) The warranty will be INVALID, meaning there is no guarantee on this product should it break, etc. Many make this mistake and think they can buy CHI products and styling tools online, but they are WRONG. If the price seems too good to be true, it usually is. DO NOT BUY THIS ITEM.
