Great Program but..... There are too many software programs out there that do this when they should be very clear from the get go. Great functionality. It had everything I needed for pdf editing. It took no time at all for me to do what I wanted to the document I was revising. Everything was great as far as features and ease of us BUT I do not appreciate or like that it said it was FREE to try and then after making all my changes and going to download it then came up that I needed to give my credit card information in order to get my document. After I declined I was bombarded by emails. I won't go back to it ever.
