I installed Ajax dock cart on my VM store and was very impressed at how easy to install and configure it was. However it did not work properly with a third party featured products template module I was using. One quick support request was all it took, and the problem was quickly corrected by their excellent support staff. Offlajn are professional, courteous, and just plain impressive. If all Joomla developers set their customer care bar as high as these guys, the world would be a much better place. Highly recommended.
