Its good for the most part - the downside is it doesnt open for me on the first try and it asks me to sign in everytime i need to print or save a doc. even though I pay for the service. Annoying that it doesnt recognize me when I use the app.

Too easy to get into FONT setup and not get out and return to font specified in document. I only wanted to get the lowest priced version, not discontinue.

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.
