OVERALL FAIR-GOOD EXPERIENCE. MAJOR FLAW: FORMATTING IS NOT CONSISTENT FROM TABLET TO LAPTOP.SIGNIFICANT EDITING REQUIRED. VERY TIME CONSUMING AND NON-PRODUCTIVE.

Using it to send IRS forms, very flexible options. Would like to enlarge the font size for printing some forms. If I use it more in future I will be interested in the webinar, but no need right now.

I have to do alot of document changes in my scope of work. This was the easiest program I've used in the 28 years I've worked in the corporate world. It's everything I have always wished I had at any given point but all in one pretty little program. Usually, theres always one feature not thought of or you dont have the option for, I didnt feel that at anypoint. In fact, I was pleasantly surprised each time when there it was in all its glory, the key option I needed. Thank you

sometimes the app freezes and takes a few minutes to load which can be inconvenient when files are needed quickly. Also some features also drag for example the signature portion. Overall great app which I use daily for my work.
