Query: Don't waste your money!

My Chi broke last week, so while waiting for my new one to get here I borrowed this hair straightener from my mother in-law. It is the absolute worst thing ever. The screws pull your hair, it is so big that you can't straighten your bangs, and it doesn't even heat up. It's so terrible that it breaks your hair and gives you the worst fly-aways you've ever seen. It is a hair destroyer. It took me two hours to get my hair to look moderately decent with this thing. Don't waste your money, you might as well buy an iron and do your hair with that, you'll probably get better results.
