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.

Pdf filler is better than Adobe Good for small simple doc editing. Adding signatures etc. I was able to get my docs edited and printed with my native software and android phone. Adobe is too picky about using their product only, with PDF filler I was able to get everything done non issues. It was a trial basis for free, I wish they would have told me that from day one to save me the hassle of going back to purchase, but really it didn't matter.

Very good tool Very good tool - I used the free trial and I'm about to find out how easy (or not) it is to escape before getting stuck in the subscription system! Update! It was very easy to cancel the subscription - confirming my 5 Star rating!

What do you like best? I love that you can store your signature in the program. Also much more professional look over using a pen to fill forms. What do you dislike? The extra level of security when logging in slows you down a little. Its probably actually a good thing as your forms are stored in the system Recommendations to others considering the product: I have tried to figure out ways to fill pdfs without signing on to this system, it was a foolish waste of time. I am not the type of person that signs on to programs like this, I always felt like they were scams. I am so very happy with this program, I wish that I had signed up for this much sooner. I am not even using all of the features of this program and Its totally worth every cent! What problems are you solving with the product? What benefits have you realized? When companies email me a form that needs to be filled out and returned, pdfFiller makes it so much quicker, easier and more professional
