Review title is but will not straighten like a flat iron [SEP] Doesn't work to straighten. The outside plastic gets really hot, which it isn't supposed to. This might work as a touch up tool, but will not straighten like a flat iron. The temp is in Celsius there is directions to get it to read in F but I couldn't get it to work. The directions that came with this were hilarious. They didn't have a translator that understood English that is why it got two starts for the entertainment value of that booklet. Don't waste your money
