We have been using their products since 2010, with no problems as far we know yet! They are very professional in every way - from customer care to product features; everything about them has always met our expectations or exceeded it (which isn't easy!). I can recommend this vendor 100%!! Nothing so far that would be worth mentioning but if you're looking at any feature which requires more customization than what they offer by default then definitely give these guys a shot. Have used almost 10+ different content management systems over past few years including Joomla!, WordPress etc., for client websites/portals.
