This is a nice module. The best e-commerce app hat I tested yet. The pro is that is lighter and faster than those big components like VM. The reason that I rated good is beacuse its lack of integration with Joomla, a good thing in the next version is to integrate the registration with the joomla site so that when a user register in the store of ecwid it automatically register in the site and vice versa.Once integrated completely with Joomla I think it would be a excellent module.
Thank you for the review. We already plan to add such a feature in future.
