I have been noticing it , it doesn't get heaten up enough to straight your hair. There is a temperature control but it doesn't work. At all temperature works the same it work at highest temperature. It's been now 1 month. But still the same. I wish I could return it back. It doesn't straight my hair. It will just give 5-20mins straight look. After that your hair will look same like normal as usual it was before.
