On the face, it seems like an extremely powerful addition to any 1.7 website. The backend has a number of configurable options. Unfortunately, unless I am missing something, there is absolutely no documentation for this calendar component. There isn't any information on how to show the calendar as a menu item, module, or article. Their website doesn't seem to offer any tutorials and all help requests are submitted and answered via email (which means there is no indication on how quickly they will respond to help requests) so for a paid product, this is a major turn off. If/when I can actually find some kind of documentation on the use of the product, I may change my review overall, but the comments about a lack of documentation will remain.
