Pros & Cons from Real Users Pros With Acrobat I always felt like I was fighting with it for control of how I use it, finding what I want. Acrobat tries to steer me all the time to what it thinks I want to do, and then pay more for some extra thing I want to do. With PDF Architect everything is exactly where I would expect it to be on the screen, but most importantly I feel I am in total control of which tools I use and how I use them. It is so well designed! I especially love the easy to use mark up tools, completely flexible and intuitive. Additionally I had a need for help with renewing to a different level, and I got very prompt and totally customer centered help. Support has been great. Prior to using this program I had used others on the market, I find this program is good and user friendly also the support is very good. In general the program works fine and it is a user friendly program. It has extensive options. You can extend it with modules such as secure and sign, which now also has new features. I use PDF Architect to add fields to my pdf's, so people can fill them in and send them back. And I can let people add there signature. I like to work with program, the functions it has. It's easy to use and it works what I need. Cons Sorry, can't think of any. There have been occasional small bugs but they seem to be taken care of pretty quickly as they disappear in the next version. Nothing negative to add. I find this program has a lot to offer if your are an extensive user. Every year some functionalities suddenly become unavailable. Then we need to contact support to resolve the issue. This happens too often and not at the time of a contract extension. I'm hoping for an upgrade that the program would detect a table and changes it into a form automatically in 1 action. Now I have to add each field by myself and that takes quite some time. Well, the changes in licesing models always bring us - the users problems Everytime it happened. The support was impossible to find on the website. If I hadn't have previous e-mails i'd be stuck.
