im getting really annoyed rite now, since my flat iron just broke....i've had 3 different kinds of flats irons within the past year.....remington wet-straight, bed-head, and tool science (which was pretty expensive-and good-until it just stopped working an hour ago!) What hair straightener out there is really good, especially for thick, really wavy hair, and will last for a WHILE?!?!? Thank you.
