I like that you can do your advertising campaign for free, which allows me to get started right away without worrying about how much it will cost in order of getting my money back from their program.
There are many similar programs out there so unless they have better customer service support than any other provider this may not be worth using as well. We use Google Adsense but we did try several different providers before deciding upon Finance Ads because our main goal was targeting people interested or looking into purchasing Financial services such as mortgages etc..
