EXCELLENT SOFTWARE, SIMPLE YET HIGHLY EFFECTIVE. CUSTOMER SUPPORT WAS ALSO IMPRESSIVE. THIS PRODUCT WILL SECURE A SAFE YET EFFICIENT WAY TO MOVE TO A PAPERLESS SYSTEM.

The filler form was OK; however, it would have been better to know there was a cost and subscription up front before putting all the time in to fill out the form. Especially when it was shown as "FREE"

Overall, the application is useful. The only issues that I have been experiencing is some of the edits I make either reappear, or are placed on top of the existing text.

Great Customer Service
I only needed the service for a specific period and thought I cancelled the service, until I was charged. I contacted customer service and gave every possible email address the service could be connected to, so I thought. None of those emails showed service connected to it, so they ended up submitting a trouble ticket. A few days later they contacted me to see if I was connected to another email address, and it was my husband's business, that I never thought about. Even though it automatically renewed, they responded that they would refund the charge.

Good company with awesome products
Good company with awesome products. Also, I even tried once to get a job as a product designer, but no luck. But that didn't change my attitude towards their digital products.
