Loving it so far. Wish the search for documents in their library was easier to find, but other than that, I've been very happy with ease and quality.

Getting to put 3 people on the account has been great. All of the features are exactly what I needed, and the editor is easy to use. I was a little wary if it would be worth the money, but I'm very happy with my purchase.

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.
