The installation and initial, basic setup is quick and fairly standard. It is in the detailed configuration and complete control you have over every aspect of the user interface and rich set of features that makes this component stand above the rest.
Also a standout is the support supplied by the developer. I had a minor issue getting my gallery to look a certain way and over the course of several days I was in communication with the developer via his support forum and he explained to me how to accomplish what I set out to do. As far as I'm concerned, this is better support than what you normally get with even commercial products.
