I have been using this T3 straightening iron for about a year now and it's the best flat iron I've ever used. I have very fine hair that frizzes easily and nothing has ever been able to completely smooth out my hair - until now. The T3 heats up very quickly, smooths my hair and leaves it soft and silky and it lasts for days. You do need to use a flat iron protectant, though, so you don't damage your hair from the heat. I also have noticed that it totally enhances both my natural and my new not-so-natural highlights. What an added plus!!! I would highly recommend.
