A must for anyone with a large catalogue that needs the ability to filter
This is not to say that you can not get support in english. The site has an ever increasing english section and google translate gets you through the rest. On top of that the support from Bram matches and exceeds that of most paid extensions.
It takes a little while to get you head around setting up the feeds within the menu but once you have customisation is pretty easy. We download feeds into a database, customise and categorise them ourselves and then upload them and this component handles it without any problems.
Great extension, great support.
