See for yourself by reading reviews on the most popular resources:
It has been very helpful. The user interface is not difficult to navigate. I am cancelling only because I do not have the volume of documents to warrant the cost. But when this changes I will certainly return.

Was a bit cumbersome. When I searched for forms, the system kept giving me instructions on how to search instead of stating that an error was made or what to do to continue.

PDF filler My overall experience with this app has been excellent! So far it has been awesome! Easy to use, many options, and easy to work layout. This app does everything it promises. I can not think of any drawbacks to this app I have not had any complications or complaints so far and I have been using for a while and quite often.

Easy I don't have to type documents every time. Just need to change the date, and other data. It saves documents and they are pretty much organized. The signature does not look good. The email looks funky. I will I can scan docs directly, and may be fax them.

I think you should ask me this again in… I think you should ask me this again in another month. I'm very new to using this, and far from computer literate, but so far I am finding it very easy & extremely useful. Thank you! Lisa Marie

Free trial review I'm a student and used the free trial. It was quite easy to use. In addition to that, I forgot to cancel my subscription, but they had an online chat that handled that quickly and efficiently which was very appreciated. Overall a good experience.
