This is a tool which I never thought I would use so much! I love it! I think the dashboard is cluttered and not the easiest to navigate, and a "strike through" option for documents would be nice to have.

Great program and awesome customer service This program did above and beyond what I needed to accomplish for my pdf files that I needed to urgently edit. Signed up for the free trial and had no issues cancelling the subscription service when contacting the customer service for assistance. Should my work orientate around paper work and documents, I would most definitely pay for this service with peace of mind knowing that this service values it's customers.

Easy and time saving I use it to fill out government and medical forms for personal reasons. It could be used for any form you might need to complete. It's very easy to use and has tons of forms available. You can upload unique forms and it works great on those too. I have had some issues finding forms I've completed.

Great customer service I didn't use the service, and my payment was refunded so easily! Most companies are not as willing to offer that level of customer service.

Overall a very good service Not the cheapest subscription, but you can upload your documents, edit them, send them via emai, fax, USPS, sms, etc. Lots of functionality and very useful. Login anywhere to continue, even via app.

Great improvement on traditional Adobe products. Good experience. I would recommend this to other in lieu of mainstream products. Simple, easy to use and operates seamlessly with other programs. It also maintains the appropriate information for future use in other forms. At times, information is lost when downloading forms from websites or is not saved when transmitting via email.
