Best Friendly user software It was great, very useful when it came to modify and add wordings to documents or even signatures. I like the availability to modify and edit your documents, it's very easy to use and it has so many features to get your documents corrected, sent, faxed, emailed and more. I didn't like when adding texts to your documents, sometimes it will freeze and close the program. Then again it was the free trial.

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.
