Probably one of the worst plugin in CodeCanyon.
No no, I'm joking. There's a bunch of bad plugins here.

This plugin, oh, how can I start.
It's badly coded, full of bugs, does not work well.
I spent so many hours to fix that crap, to make it work until changing to a more professionnal quote plugin.

To make it short : DON'T BUY THIS CRAP. This plugin should.... no, this plugin must be recoded from start.
