A great Program Its a good program, but it takes a few minutes to get use to the actual text placement for your fill in. I did not try the signature feature. I will continue to use this program. I'll use it more often as I get use to it.

I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named **** was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)"

Support team is on point. I was charged for a one year subscription even though I had cancelled before the 30 day free trial was over. The support team immediately resolved my issue. Within a couple of minutes. Special thanks to John.
