Tornado: Waste or Must Have?

I got home this morning, and couldn't sleep so I cruised the boob tube and ended watching the infomercial for the Tornado. Has any one even tried this thing? looks like it works, but it seems to me all it does is block the airflow. I want to hear expierences with this thing, if its a must have, or don't waste your money. they make a good argument for it though...

I did some research into Tornados, and they don't add anything. You can find reviews all over the internet, just Google it. Don't waste your money.

Well, if you buy it, you're putting money into the economy, but that's all.

Tornado is just another "snake" product. In best case it doesn't reduce power.
