It allows creating forms quickly in few steps with inserting predefined or custom fields
I use it as a contact form for customers, and as a form for applying participants to education and it fulfils my needs.
It needs improvements for formating fields and customization of presentation on website.
Also, needs more options for sending notification mails to subscribers and administrator after receiving submits.
I think that this extension is in process of development, and taht it will be only better.
