The Vidal Sassoon Ionic hot air brush is the best thing ever, it works great for me and makes my hair smooth and straight. It is quick and easy to use. Just do not touch the metal part, it is hot. This is the fourth one I have ordered after a year or so it burns out, I was using it every other day. Worth the price and quality is good.
