It's somewhat costly, but it works. I have no idea whether it's worth it. I needed to get something done, and it was easy to find, so it was worth it to me. I certainly was glad there was a half price sale.

It's good At first it can be a little overwhelming with all the options but once you get the hang of it is pretty essay. I really like that it saves all your files too, just in case.

It's very easy to create It's very easy to create, edit, share, get website code, and sell these forms. The reason I am giving a 4 star instead of 5 is the price.

What do you like best? With a lower monthly fee, I can log in and have the capability to use the editing tools to update and sign my files with ease What do you dislike? I do wish that notification would go out to my email if or when the website is updating the platform What problems are you solving with the product? What benefits have you realized? With any update that has adjusted the layout, I have been able to get ahold of customer service for clarification. Although the 24hrs wait for a response is frustrating
