The Instyler is okay for me didn't do as well as i thought it would. My straightener i have right now is Plug in Ged works good. Price range not to bad but for me i really love the Chi straightener works wonders in my hair.
I have one very similar to this one http://funadvice.com/r/15krjt0e3md & it works wonderfully.
I have the chi and it works good
I hated my instyler
