I am retired and use it mostly for medical forms. A little difficult to learn how to begin but once I figured it out everything worked just the way I wanted and I learned more as I went along.

ease of use could be a little better The signature feature is wonderful. Tabbing around the form is easy. It makes signing documents very convenient instead of having to print them out and sign and fax or send back. It seems like each time I try to do something new, it costs extra. Example is signatures. Only holds 3 signatures.
