These straighteners left my hair smooth, straight and silky and people commentated on the difference in my hair. Perfect substitute for GHDs. There are only a couple of drawbacks; the body of the straighteners gets very hot when you're holding them, and there's no off/on switch - they can only be turned off by unplugging which is a nuisance for me as I like to keep them out and available at all times without having to crawl to the floor to find the plug socket.
