What do you like best? PDF Filler is extremely easy to use and navigate. I've never experienced any lag or difficulties in using the software. Signatures are easy, dates are easy to inpute. What do you dislike? You don't get to really choose where files are saved when you download them. What problems are you solving with the product? What benefits have you realized? I've been able to easily fill out and save consolidation agreements, settlement letters, and anything else that I need and don't have time to print out and sign just to have to scan it in. It's definitely a time saver!
