See for yourself by reading reviews on the most popular resources:
Took forever to figure out it wasn't free. Here I thought I was filling out a form to print and filled it all out then said I need to pay. Very frustrating
2017-04-12
It was fairly easy to search out IRS forms but then you find out they're not usable because they're in Red!?! Also it said if you paid for a one-year subscription you save 65%, but the yearly cost was exactly the same as paying monthly and you didn't know this until you processed your payment???
2018-01-26
I did not like the fact that when you decided to make it a service that charges you money, there was no warning. It forced you to pay if you wanted to keep your documents. I'm past that now and I am really ENJOYING it now that I am a paying customer.

AWESOME program but too expensive
AWESOME program, but the monthly cost is WAY too high. Should charge customers a more affordable price of $10/month. And stop trying to force us to pay for a whole year up front -- what if I don't need it for an entire year? Fantastic features, easy to learn, a pleasure to use. Just TOO EXPENSIVE.

Great to mark up documents.
I like this software and they have a money back guarantee of 100 days I believe.
I use this product to mark up documents and sign. I like to keep everything that I do 100% electronic, so with products like this, I am able to do so.
I haven't found anything wrong with this software. It is great for any industry who deals with electronic PDF files.

Very straightforward .pdf editing
Very straightforward .pdf editing! Easy to use, not too many steps to getting my edited .pdf documents right away, speed is important for work hours.

some of the forms are the same but pdfFiller has them in different names. I keep filling out the same form over and over, thinking it's a different one. confusing.

What do you like best?
PDF Filler helped me when I inherited a bunch of learning material that referenced outdated case studies and I needed to update for class. Because I didn't have Adobe or photoshop, this was a great alternative to help me quickly update the decks. Erase text allowed me to "white out" the outdated information without compromising design quality.
What do you dislike?
If you are adding text and trying to use text box, it will show a box around what you replace. When using the text feature to replace text, of course, you won't have an exact match unless you know the current document's font and size. Nonetheless, PDF Filler makes it easy to drag, drop and align so that you'd have to really stare at the document to notice the differences between the original text and your replacement text.
What problems are you solving with the product? What benefits have you realized?
Needing to edit PDF's that were previously created, and provided no access to the original version. Better ease of use//less learning curve than Photoshop. Cost-friendly alternative to Adobe.
