I just needed to do one form, so I chose the one-month subscription. It worked great, but it was not clear when I purchased that ONE month, that I would be setup on further automatic monthly payments, otherwise I would have opted out of that. Now I'm considering filing a formal complaint, unless my $20 renewal fee is credited back to my account ASAP!
Jesse
Very useful. Some issues with mobile devices filling out fillable forms and not all the data showing up on the completed form. Loading times could be a little faster. Also, I shouldn't have to give the app approval to access my email each time I upload a new file from my gmail account. Once should be enough, and the connection should be remembered, but it's not.
Eric P
Great Software Good experience but we just need the time to learn more. Ease of use once we know what we are doing! Need to contact Customer Support for help as I believe there are way where we need to know more.
Lori O.
Excellent product never had an issue so can't tell you what support is like. Upload, fill and print Quick and easy to work with. Have used other pdf products and this is best for the price. Easy of use and no software to download. Cloud storage is great my documents are all stored where I know they are for future modifications. Worry about encryption and security of stored documents but most of my work is not confidential so that is one reason I use it.
