It's made my reporting easier. It may be that I don't know everything to do on this site, but it would be nice if I could resize the boxes on my form.

So convenient and easy
I absolutely love how easy it is to pull a document and fill in information or sign and send back out. This is super simple for the constant paperwork I must complete.
It is difficult sometimes to get the size and format of wording to fit correctly.

It was easy to use and did want i needed to do. However, we starting I selected monthly only to discover it is charging me annually after registering. I didn't like that. Kind of expensive at that rate.

very useful and easy to use!
Very useful and cool for filling out paperwork/forms online without having to print them out and scan, or changing the documents format to fill it out.

Their Customer service is superb.
Their Customer service is superb.
I was charged for a subscription which was, to me, erroneous as I had merely tried the sofware and immediately cancelled.
But on contacting customer service I was pleasantly surprised at the speed of their response and at the total refund with no qustions asked.
They go beyond the call of duty, many thanks.

What do you like best about the product?
It's the best tool for PDF editing I have found so far
What do you dislike about the product?
Too expensive if you're not a business user (the price is too high for myself when I need the tool for a few times during the month, so it doesn't worth the price)
What problems is the product solving and how is that benefiting you?
It works perfectly as an editor, so I can easily change my documents with minimum effort.

Thrilled with this app!
After I found this option, I've been thrilled with it. No more prints and write; now I do everything directly in the computer. Less environmental damage, no ink and no papers. Loved it!

Great customer service and solid product.
I don't usually leave reviews, but this product deserves my time.
Works very well in filling PDFs. Typing, checking boxes (using the checkmark or "x" feature), filling out tables, etc. Saving and editing again works well, though it isn't entirely intuitive the first time.
Customer service was absolutely awesome! I realized, after signing up for a paid subscription, that I no longer needed the service. I cancelled online (or THOUGHT I did), but I must've had a glitch. When I got billed, I called and they issued me a refund no questions asked and zero hassle.
Customer service was incredibly helpful. Product was great for filling out multiple long pdfs that only had slight variations (saved a copy and changed only the fields that I needed). Easy to use and quick to learn.
I cancelled my subscription only because I realized I wouldn't be using it enough to justify the cost. Life changes!
