wow 330! I am using a jilbere porcelain flat iron it goes up to 30 I'm not sure what 30 means but it's really hot so I stick to 20-25 it's still hot but it's a safe temperature and my hair is not left smoking afterwards lol!
Hey, I use the same one too. It's the inch and a half one and I also use it at 25!
Although, honestly, I should set it a lil lower next time. I bought this flat-iron 2 weeks ago, so still getting the hang of it. I got some great results though! What about you, based on your own experience with it?
