I did not like the way my card was charged the $120 initial annual fee. I only wanted to pay by month. That was misleading and I did not appreciate it. If your going to offer the monthly plan, offer it, make the wording more clear. don't try and trick people into the yearly plan and make them go through customer service to get the refund. The reason I give four stars is because (1) the customer service rep was so helpful in getting me my refund back and (2) you have an awesome product. It is really working well for me.

Very satisfied so far. Have not yet utilized the notary service but plan to do so. Very happy editing PDFs. My only complaint is that it's far too expensive for my needs as an individual. I can see how it would be well worth it for a business, but in my case, I will likely cancel after a month because I just can't afford it. Please consider a cheaper option for individuals &/or sole proprietors. That said, it's a great service -- far better than others I've used. Great job.

working great so far, any difficulties are due to my lack of knowledge. My only suggestion is to hire one really dumb guy, and make it so its easy for him. Would you like me to send my resume'?

Easy to execute the changes needed… Easy to execute the changes needed without much instruction. Saving in the pdf filler on One Drive was slow (undoubtedly Microsoft's problem).
