See for yourself by reading reviews on the most popular resources:
I experienced quite a steep learning curve. Meaning, the directions I would have found easier to follow would be in steps...step 1, then step two, etc. In other words, the program was really user friendly to first time user. Also, I thought I signed on for a5.95 one month contract that I could cancel at any time. Why am I being charge19.95 Please answer this question. Thank you

It's great! Only problem I had was trying to erase a hi-lited area I accidentally added. The software wanted me to pay for an upgrade for the eraser which I think is ridiculous guys. Other than that, awesome.

Great for businesses. Simple, yet powerful tool for anyone who finds themselves away from their desk often. I can easily fill in text fields, E-sign and add pictures to my pdfs. I've also used it to print, email or eFax pdfs and docs.

One time using pdfFiller the first time… One time using pdfFiller the first time saved me time doing a very basic operation (checking off fields when I was entering information from forms into another program). I have used the other program for over 15 years but recently moved from a PC to MacBook Pro. The program for Mac is harder to use than the PC product. I have spent too much time and frustration with that program. After one use, I had to spend much less time with little frustration. I hope it continues as I using pdfFiller

This is the best PDF program Ive used This is the best PDF program Ive used. Ive long wanted something to compete with Adobe and this is it. I love the ease of using all features, especially the editing/adding text option. This program is top tier! As a healthcare provider who has to often complete forms for patients, this program exceeds my expectations.

This is a great service This is a great service. Easy to use. Easy to upload, edit and share documents you need others to review. Also extremely easy to fax and there's even a service to mail the document within the U.S. from your computer from anywhere in the world. Highly recommend it.
