I like that it is easy to set up, so we can use NIMBLE BI for our internal reporting needs which are pretty complex (we have over 100 sub-sites with many customizations). The interface could be more intuitive but this isn't really an issue as most users will just need basic functionality without needing advanced features such as "advanced" data filters or drill downs of reports. Reporting from multiple sources using one master source has been greatly simplified by putting all these pieces together in ONE tool!
