facebook ads intelligence/spy tool

Hi, i've been doing some reasearch trying to find a good spy tool for facebook ads, i found many, like social ad ninja, adfox, and adicted, based on the reviews i found, the the only one that seems worth a try for now is adicted as the first 2 are forgotten and aren't maintained anymore, does anyone in here use adicted and can give a quick review? or any other tool they can suggest ?

What functionality are you looking for in a ad spy? You'd like to know what your competitors are advertising?

yes basically, see ads, the (approx) audience the ads are targetting, how long they are running etc
