Professional straightener that will curl, straighten, & make wavy hair?

i have an instyler. (you know, the one on the infomercials) and i think it is awesome. my mom got it for me and i just thought i was supposed to use it like a regular hair straightener, so at first i thought it was just a joke. but if you actually watch the infomercial and do exactly what they do, then it will work. i love it. it makes your hair like instantly soft, shiny, and straight. no matter if your hair is frizzy or not.
