Love this program! I am new with it, but it makes my paralegal position ( I do public benefits advocacy) much easier in filling out forms that are not fillable on the Social Security website.

I can't verify that my completed forms are actually sent to recipients. Programs keeps requesting me to have my e-mail verified but no code is ever sent to my e-mail.

Easy to fill forms!
This software is very easy to use, I'm able to fill forms we use over and over again. Adding signatures is simple and seamless.
Switching between pages. I'm used to rolling down with my mouse. I also noticed a bit of delays, but it might be our network connection.

Amazing customer support
I had to contact customer support because I, out of my own negligence, got charged for one of their products. They were extrememly helpful and resolved the issue, even though they had no reason to do so (except sympathy). Extremely nice customer support. Definitely recommend.
