slows down site, does not work, is kind of demo for buying pro

After the plugin activation the site load was about plus 20sec
the attributes, colors in my case did not filter correctly.
From my point of view it is just another one of those millions pseudo free plugins which promises even more when you buy it. Should not be here but only on codecanyon.
by the way, the documentation is poooor as well.

to devs: make a real wp plugin that works good then I buy a “pro” version
