Great for easy form creation for end users
I love that you can make not only nice, user-friendly forms, but they become user-intuitive with this product. This takes the process ahead of just creating a Microsoft Office form, but allows you to create sophisticated forms that can be filled and even electronically delivered.
Often the layout gives me trouble or won't let me create form boxes in the appropriate area because it keeps snapping them to the grid, which might not automatically line up to my form fields as well.

The product is great and very easy to use. I had started a free trial for one time use, but forgot to cancel it and was charged for a full year, but when I contacted them they refunded my money straight away with no questions asked. I wish all companies were as good to deal with as this!
