I thought it was great & easy to use. Only reason I didn't give it 5 stars was I would have liked to have known I had to buy a subscription before I could print my document. I probably won't need to use it again in the foreseeable future.

I love the ease and speed I can convert docs to fillable pdf files. I am not so happy with repeatedly being asked to rate the features, take a survey and attend a webinar.

It was just what i was looking for...im not very computer literate but WAS NOT hard to learn. I do think a few features could be added or made easier. I WAS NOT HAPPY WITH THE COST. Its mighty ridiculous! For the amount of money i spent and the length of time... S***, unless you are in the business of "screw ups" "uh-oh"ers, the presidents Secretary for his twitter account...or a lawyer. I don't think you get enough time for the cost. And VERY UNSATISFIED with the small print that is located UNDER the nice AFFORDABLE FAKE SALE PRICE at the beginning of the website
