This app looked promising when first installed, but like many others it is limited only to authenticated users which is unfortunate. It looks so promising for the ability to scroll company "news" via the public facing website where in my opinion this type of information would be more desirable. It was also very easily customizable to be used to scroll through products or services as well, but again doesn't work on the public facing website.
For authenticated users, however, it works well and is easily installed and configured. I hadn't got into all the details to notice any severe limitations (minus what was described above). If it were enhanced to allow anonymous access or a sibling version was created that did so, I would be inclined to give a higher rating.
