IM IN THE WORST PREDICAMENT AND CANT AFFORD LEGAL HELP. THE ONLY CALMING FACTOR IS FINDING WHAT I NEED ALMOST IMMEDIATELY EVEN HARD TO FIND BRIEFS AND CASES OF SIMILAR NATURE. ALSO IVE LEARNED QUITE OF FEW THINGS WHILE SEARCHING THAT CAUGHT MY EYE, A PLETHERA OF KNOWLEDGE. I THANK YOU, YOU HAVE NO IDEA THE COMFORT IT HAS BROUGHT AND THE FEELING IVE GOTTEN BY DOING THINGS ON MY OWN. MANY PRAISES IN FUTURE ENDEAVORS.

Overall, this product is good and I would recommend it to a friend. Like it over Adobe.
When I played around with the trial, I liked how you had many options and the program layout was nice. Love the ease of use when trying to alter a pdf.
I wish I had a longer trial period and sometimes I could not save a file causing me to save over the original file.

The product is great and very easy to use. I had started a free trial for one time use, but forgot to cancel it and was charged for a full year, but when I contacted them they refunded my money straight away with no questions asked. I wish all companies were as good to deal with as this!

Hands down best ever!
This service is absolutely, hands down, beyond the shadow of a doubt one of the best services that I have ever utilized for document fill-and-sign, templates and basic document editing. I love the service, it's ease of use and especially the price point is unbeatable. I would recommend this service to any of my colleagues in law and especially in the real estate industry.
