Great. Still getting used to it though. But is very helpful indeed. When I paid for this it cost $120 but my credit card was deducted $170. I am still waiting for a response please and a refund

I really like it so far. The snap to grid text editing is fantastic. The cloud options and email sync are perfect. Nice job. The UI is almost exactly like my Neat scanner software so it's very intuitive.

The only reason my rating isn't a perfect 5 Stars is regarding getting an a document notarized online. Your website says it will be at no cost. But when linked to the vendor notary person, she said the cost is $25. When I contacted your company a couple of times, it was indicated someone would get back to me w/ answer. But that never happened.

Great tool for PDF mistakes
Good experience, I really recommend this for people who need a PDF edit tool
It' easy to use, few and useful settings that can really help fix a mistake or even save the document in a different way
I couldn't find the go back tool for a minute but it's actually pretty simple and helpful
2019-02-26
If you have forms to fill out electronically, this is the website to use. It is simple even for those not great with tech! Customer service is also very honest and helpful as far as billing, etc.

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.
