I have not been able to figure out how to use my mouse and just scroll/roll thru the doc. I have to go to the left and click on page 2, to get to page 2, I can't just use the roller on the mouse to move.

It runs smoothly and quickly. It appears to have every feature I need in my daily work with PDF files, except one. It would be a fully completed utility if it included options for arranging/rearranging pages in PDF files. If it has that feature I am unable to find it. With this feature I'd rate it 5 stars.

its good so far however I ordered it because it said it was $10.00 a month and it turned out to be $30.00, I guess that's only if you pay for the year it would've been nice had that been made clear before I put in my cc info

I think it's very useful but expensive and the basic subscription does not seem adequate to perform some of the things needed at that initial level for that cost.

Very quick, efficient, and easy to use. I don't mind paying for the annual subscription because I know I can rely on my documents getting done with no messing around!

Greatest PDF Library out there PDFFiller has one of the best PDF Libraries I have ever come across. every possible template you can think of, you can find. This site deserves every star in this rating. In all honestly this is even the first time I EVER wrote a review, but I am doing it just so the team behind this website knows that there are people who are grateful for your site, and your work. and I would like to speak for every single one of the ones who are too lazy to leave a review, but you have saved us countless hours of what would otherwise be, a lot of research to try and complete the tasks we had at hand.
