I bought one of these after seeing the ad on tv. They really seem to work. After having it plugged in for a month, my tele-marketing calls have dropped off to none.

I live in Indiana and starting Jan 1st, you can get on a list that all telemarketers have to buy. If they call you they can be fined up to $50,000 (or about that). Between these two items I hope that I'll be free of telemarketers.
