I have been using straightening irons for nearly two decades, and this model is one of the finest. It is the one I prefer of all the types I own and produces sleek, bone-straight locks on the frizziest hair. Previously, I purchased a competitor's 'professional' straightener that was three times the price of the Revlon and is now stuffed in the back of the bathroom cabinet -- the Revlon beats it hands down! My No #1 choice to combat the fizzies!
