content: Ive used the free version for 5 yrs it has worked perfectly for reading commenting filling and signing PDFs. Ive had the paid version just over a 1yr I use it for editing PDFs. I wish it was easier to delete a whole page but otherwise Im happy with functionality. Our contractors use it to fill out forms. They have a mixed experience. Some can use it to fill with no issues. Others have constant issues. I assume these are mostly user related as they havent been able to reproduce issues
