Easy to use and has multi functions that otherwise you would need to purchase separately elsewhere. I gained TIME, thus I was on time with my tasks, and met deadlines. Very easy to read, highlight, insert comments (etc), insert and replace figures in pdf documents. It has saved me TIME! I love that it offers features that make manipulation of multiple files easy and fast. I also like the electronic signature option so documents look very professional.
