The best facebook pixel tracking plugin

I have sorted and installed all 5 major widgets that advertised as facebook tracking plugins here on www.remarpro.com. From all of the 5 this is the one that does exactly what I want eg:
– automatically add the correct event to the pixel when used in important pages such as: order completed, cart, etc
– ability to add custom tracking to every page when you are creating the page.
– THE MOST IMPORTANT FEATURE: it dynamically adds the parameters to all the tracking events eg: for purchase event it adds: product ids, and cart value. This means that you can trace exactly what was the ROI for each campaign directly from Facebook.
A MUST HAVE!
