Having used different components for forms, I must say this is one of the best you can have. It's not only very flexible in many ways to suit your needs, it is also very easy to use! Anyone can create forms with this component in no time. And if there are some problems or questions, just create a ticket. You'll be answered in a very helpful and friendly way, fast.
I have tried the normal version and switched to the Pro version. I advice to immediately go Pro, it's worth it!
