It's a great program, but it can be a bit glitch-y when trying to fill in information. A minor problem, but it does get in the way of having an optimal user experience

I have only used it once before and I like it. Some of the fill-in spaces are challenging, but I'm sure it is because I haven't mastered the software yet.

This is a great service
This is a great service. Easy to use. Easy to upload, edit and share documents you need others to review. Also extremely easy to fax and there's even a service to mail the document within the U.S. from your computer from anywhere in the world. Highly recommend it.

The PDF filler is amazing
The PDF filler is amazing. It has solved me in so many situations since being in isolation due to the fact that I do not have a printer. So easy to use. The only feedback is the date component is fiddly and doesn't always work but other than that - perfect.
