First of all, I never wrote a review for an extension before. I choose this extension after many evaluations and comparisons with others. The demo site shows every functions that this extension can do. I'm very satisfied of my choice. I'm not joomla guru. I had a little trouble in my installation but customer support helped me quickly. They are fantastic, within 24 hours they made all customization I asked, with no additional cost. If I had to find a flaw, I think they have to improve translation system.
