I justed started with DNN and purchased these modules to easily extend my site. The modules have done exactly that and have more features that I expected. I had some minor issues during my first setup mostly due to my DNN inexperience, and Chad at Data Springs helped me figure out what I was doing wrong. The support tickets say 24 hour turnaround, but at times it felt more like being on an instant chat. Being new to DNN the support is probably my favorite part of this collection.
