I was very upset at the beginning but after contacting customer support the problems were resolved and and I am happy I was able to complete my forms for my disabled grandson.
BRENDA A
Like the program, although it does seem complicated. However, I keep receiving error messages when I send docs to be signed, and when I send it in I receive a message saying it is on our end. I would like to use the program for many things, especially getting signatures, although it seems that isn't included now and is additional cost, so I may go to authentisign

Easy to use. It's good that we have this product cause we can just sign PDF's without printing. Sometimes it's hard to place the 'typing icon' in the right place for filling in information or data.
Jason B.
