Very Quick, saves me a lot of time. I regularly get pdf's that need to be completed and sent back. Now I can upload, fill out and return in a fraction of the time. Since the data is typed, I never get a question about what I wrote.

I like the program. I did pay for it, so I feel that I should be able to upload pictures to the file. Uploading images should be included in a basic membership. I still like the service.

great customer service - sam great, easy to use, saves us a fortune on an extra phone line for a fax. Great customer service, I always use live chat and get answers and resolution within a few minutes. I have only had to use support 3 times in a year because the program is so user friendly.

Very satisfying!!! It has been a very helpful tool to modify and to fill up forms related to my work. The only thing I regret is not have been subscribed earlier.
