I purchased this flat iron to replace the other Paul Mitchell Flat Iron I had. The first one started to short out, after about a year. I would have to keep turning it on an off in order for it to stay heated. I then purchased, and returned, 2 other flat irons that were very unsatisfactory, so I decided it was worth it to go with another Paul Mitchell. Even if it lasts for only a year, I love the way this product straightens and puts shine into the hair. It also does not catch the hair, like many of the other flat irons. Your hair just glides right through.
