Using it heavily. Very advanced, with a ton of features, although a bit buggy in image handling and export/import, but nothing that can't be overcome.
This is the best one I've ever used. It's a shame that they haven't moved on to a next version - I'm hoping to see an updated version soon.
Lacking some advanced features (that can be found in more expensive modules) but overall very good for form generation tasks.
Excellent.
