A few months ago I signed up with this offer. I received the free $20 worth of traffic. But a couple months later I was charged $32 because I forgot to cancel the ad after the free $20. So my campaign was still running. There's no telling how many people forget to cancel like I did. Got to say it's a good way for them to get alittle more money from you.
Traffic wasn't really that good either. If you do it put a sticky note on your computer screen to keep checking.
