So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!

On the first day of use, I thought I had lost all the data I entered. I received help via a chat and verified my data was intact. This is going to be an extremely useful product for me as a consultant.

I used the trial to fill out an application, but had no reason to subscribe further. The software is easy to use and very useful. I attempted to cancel auto-renewal but i got an email saying I was charged for a year subscription. After contacting customer service, the charge was cancelled within 5 minutes. I was impressed with how quickly and thoroughly they responded to my issues!
