Very helpful in my law practice. Ease of filling out a variety of documents. Easy to use. I like being able to switch from the wizard option to the self fill-out option. It is usable with all the legal forms I fill out. I do not like how I cannot change font size when using the wizard to fill out form. Sometimes I don't have enough room in the space to type what I need. I also don't like how you lose what you have filled in if you switch from the wizard half-way through.

Great support from the team, especially Kara Over two days I talked to several agents. Kara was able, with great patience and time commitment, to solve my problem. Anything I have paid for the program and year subscription was was worth the service I got. I hope she is recognized as the best! Thanks to the program but most of all to her. Great job!

What do you like best? Ease of use, quick editing, icons help with the direction on what you are looking for. What do you dislike? Editing some previous text, automatically changes font. Recommendations to others considering the product: Best buy for your dollar. What problems are you solving with the product? What benefits have you realized? Saves time using the editor rather than print out paperwork to fill by hand.

Fast and effective response When I contacted them through their Chat feature my problem was resolved there and then. Instant response, and then follow up emails to make sure everything was ok. This is how customer service should work but so often doesn't.
