Anytime a client uses this, I sigh a relief Excellent for contracts and any paperwork. PDFfiller is super easy to use and takes the headache out of mundane paperwork filling. Kudos! I dislike that more people do not use it, if you aren't using this, what are you doing?

Very helpful in my law practice. Ease of filling out a variety of documents. Easy to use. I like being able to switch from the wizard option to the self fill-out option. It is usable with all the legal forms I fill out. I do not like how I cannot change font size when using the wizard to fill out form. Sometimes I don't have enough room in the space to type what I need. I also don't like how you lose what you have filled in if you switch from the wizard half-way through.

I like that I don not have to decide… I like that I don not have to decide how big the text box needs to be, it does it automatically. I use it for work to fill out my time sheets or edit PDF files and it works like a charm.

I'm working on several files for which I need to be able to type in the answers as my hands have arthritis in them and that makes it difficult to write. The instructions could be a little clearer. To be honest, I'm a new widow and I wasn't thinking very clearly. I haven't taken the time to read the online instructions so my navigational issues are of my own neglect. I think you have a wonderful product actually.

The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
