What do you like best?
I enjoy very much that I can scan in documents and then fill in and add things to them easily.
What do you dislike?
Very little. But sometimes I find I accidentally click on the up/down bar instead of the buttons. Also, some of the buttons are not intuitive, but trial and error works well, and mistakes are easily deleted.
What problems are you solving with the product? What benefits have you realized?
I used to need a type writer (or hand write) sometimes still to comply with using the forms given to me by the government. Now, I can upload them and use the computer. Much better.

What do you like best?
It works. Easy to use platform. I've subscribed for several years and they continue to make improvements. I tried docusign and this was just as good.
What do you dislike?
I don't like that it won't link up with business accounts on OneDrive so I can't store my files on OneDrive. Really would be nice to have them fix that! Also for some weird reason, the system only can connect with personal accounts. Sometimes, it's not easy to find my documents. Finally, the plug-in for Chrome doesn't always work well. Usually, it's just better to go into the app itself.
Recommendations to others considering the product:
Compare the functionality you need to what it offers. I suspect you'll find it's sufficient.
What problems are you solving with the product? What benefits have you realized?
Send out paperwork for signatures and fill out paperwork online instead of printing, signing, and scanning it.

Provided ease by timely consistence and effortless interface in preparing & modifying quality forms. Ease of use. From downloading to modifying. Short learning curve. Provided easy solution to modifying old forms by scanning/uploading and easy modification. From what little I used it to create new forms, more flexibility would have been nice for import and modifying images. But since I rarely used this program for creation I may not have explored the features properly.

A certificate contains a public key.
