The program interface is OK but it could be a little more iterative. A form I was completing for the TSP TP77 and the TP76 did not place the letters and numbers (characters) in the exact center of each box making the document a little harder to read. I know this for sure because I have completed the same document using TSP website filler with the document are available. This would be easy for the company to fix this but they check their forms before making them available. But the overall online forms filler program works well and saves completed forms easily and has a generous library.

Works pretty awesome. I edit pdfs on the regular using this software and it's very fast and easy. It's very easy to edit pdfs. I have to edit multiple pdfs and I use this software. It's very beginner friendly and its a simple tutorial to show you exactly how to edit the files. When you edit the text it's never the same font as the original pdf so it's very noticeable. If that's not a problem to you then you'll love this software.
