See for yourself by reading reviews on the most popular resources:
Sometimes its a little difficult to navigate around especially for making an application, but once its set it up it works well. Ive noticed 2nd pages are difficult for customers to see and fill out. Wish there was something that would prompt them to go to it.

Great app
Great app - really easy to use. Doesn't change the quality of the document. Probably won't pay for it long term - I would pay £1 or something everytime i wanted to use it though...

I made a mistake and bought a year subscription instead of one month as I needed, I immediately emailed customer support and thought I would be waiting days for a reply if I was lucky, but to my surprise I received a response within 2 minutes. She offered to change my subscription and refund the rest of my money, I of course excepted and they changed it immediately! ***** ******** for your amazing customer service! And your forms, that have been time saving!
