Great product, have not really used much but I got it in anticipation of a pdf filler. Plus the price is great. My son is really happy we have it makes his applications look amazing.

Like that it remembers where I was in filling in the forms. Filling in was a little awkward on the government forms I was working with. Would help to have a built in tracking mechanism to determine progress.

Everything has been great, with the exception that it takes a while to open up the documents on mybox. There should be a feature for ''QUICKVIEW" of the document you want to open.

PDFfiller is so user friendly. It helps immensely as a private practice owner where I need to fill-in pdf documents, convert to other formats, and insert verified signatures. I would recommend to other business owners.

Easy to edit. I had a little trouble completing the form correctly but it was my fault. I went back and made corrections easily and all seems fine.
