So far, i'm impressed.
I have been testing and now using this tool solidly for a few months at the point of writing this and so far it has been able to handle every scenario and weird detail that I need from. Support has been very responsive. I asked about a feature and they said that it was not available. Came back after the weekend to find an email that said they had built what i needed for me and made available for everyone. The form builder is extremely flexible and because of the way it is designed has the potential to be so much more than just online forms. Great work FT team!
