Query: May Catch You On Fire

I have had this curling iron for almost six months, and while the heat setting is a little frustrating, I had relatively no problems. Then, today, as I was getting ready to curl a section a hair, I heard a loud pop and saw a pretty big spark fly from the handle. I am relieved that I didn't actually have the thing in my hair when this happened. I would not recommend anyone to purchase this iron, regardless of the price.
