Query: Wow...this does nothing

I bought this hoping that I could get rid of my flat iron, but this is nothing more than a hair dryer with a comb attachment turned sideways. The tension settings either pulled my hair too much or didn't put it at all. My hair looked just the same as it would have if I had used my hair dryer and a comb attachment. Save yourself some money and buy a $5 comb attachment to put on your hair dryer. I have AA relaxed hair.
