This has been very helpful. My only problem is a tried to sign up for a monthly membership and I ended up getting charged and receiving a year membership. That part is a bit confusing.

Good layout and simple to understand Good layout and simple to understand. However, while editing I realised that it does change the original size of the item when it is converted the format.

It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.

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!
