Very quick, efficient and courteous customer service. My elderly mother subscribed to this service and couldn't remember why. I explained the situation via emails with Customer Support and they refunded the annual subscription fee after I verified a few details. I really appreciated their understanding and quick response. Now...I have to go unplug my mom's computer. :-)

Easy to use. I have to STUDY the layout to find what I want. We are not power users of this product. The webinar might help. The pricing you impose presumes that I use a lot of features. I wish you had a price structure to low end users who seek to have a few simple forms filled and signed.

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.
