Just a straightener, and not a very good one at that [SEP] I thought there was more going on here than just a straightener with a rounded casing, but that's all this is.  A regular old straightener.  And not that great of a straightener at that.  It does not curl my wavy, relatively easy to curl hair at all.  It does straighten it, but leaves it looking a bit dull and crunchy, not smooth and straight like my normal (not expensive) straightener.  I can sort of get curls with my regular straightener but thought this would make that process easier somehow since it's called a "curling iron" in the description, but nope.  Save your money, there's nothing special going on here.
