I bought flyer as a part of a template from a vendor, and can say I am extremely satisfied with the capabilities it provides and the quality at which it does so. It is elegant and easy to use, and adds value to my joomla based website. The module is easy to configure, and once that is done, the component becomes the only thing you need to deal with to update content. The categories feature in the component makes it easy to handle so you dont even need to check the module again.
One improvement I wish to see soon is supporting K2 items as well as conventional Joomla articles.
