Query: Worst straightening iron I've used.

Though this is only the second straightening iron I've ever used, it is by far worse than my other one. It didn't dry my hair when I tried to dry it when it was wet. No matter what setting I used when my hair is dry, I can't get it nearly as straight as my other iron, and it's not very good. It takes a little over thirty minutes to straighten my slightly curly shoulder length hair with this iron, where it only takes fifteen minutes with my other iron. I honestly wouldn't recommend this iron to anyone. I found it to be a definite waste of money.
