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 is 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 is called a curling iron in the description but nope save your money there is nothing special going on here
