Flat iron hair straightener features?

What features will you look for when you buy a flat iron hair straightener? thanks!Flat iron hair straightener features?
ceramic, tourmaline, nano, knob to turn up and down heat, swivel cord (this is a biggie).





It also depends on your hair type, some of the cheapo straighteners will work, but it's better to get a more expensive one with true ceramic plates, not just a ceramic coating if you have curlier hair. :)Flat iron hair straightener features?
