The organization I work for has a TON of forms online and BreezingForms has make it so easy for us. The videos are a great help. Easy Mode is, well, easy! The included features and ability to add scripts and finely control the forms is fantastic.
Probably the most important thing is the quality of service I have received, both on the forums and through email. It is so great to have someone available that committed to their product and their clients.
