We've installed this on a joomla 3.x site. The overall setup is straightforward, although as others have mentioned there is no documentation. For the most part it works well. However, I think people are interested in this for its responsive capabilities. Unfortunately, they have not made the caption text responsive. So while its great that your slide image will scale down on smaller screen sizes, the caption text will not. You have to be knowledgable enough to set up your own media queries to handle this.
Also there has been reported an issue of all of the slides appearing briefly during page load. We have this issue as well. This may be a show stopper for some.
