I think my straighener is about to die. I have had it for several years. The light keeps flickering and it doesn't seem to be getting as hot as usual. Does anyone have any good recomendations for a new one? I don't mind shelling out a bit of money since I do use it a lot and they last a while but I want one that works. I think mine is FHI brand or something like that... got it from Ulta. I have hear the Chi (?) brand is good... any suggestions?
