It looked very promising, but "importing demo data" means ALL demo data. There is no way to select which template you would like - you know, the one you actually wanted to buy.
Even without WooCommerce and only one of the three sliders installed, this theme creates 100 new pages, 12 new posts, 141 tags, 4 categories and 250 images. That equals 30.000+ new entries in your database.
Contacting MF support about this resulted in "just delete what you don't want". Sure... Who doesn't look forward to deleting 29.950 database entries manually?!
Not importing the demo data gives you no default template, so you are basically just installing bundles plugins.
