Mostly I am thrilled with this service I didn't know I needed... until this week... and I needed it twice!! The form MC 030 was glitchy when it came to cut and pasting and editing the comments section. My only complaint.
2017-08-04
It's easy to use, I do like it; but it is a little expensive, $80/year is a lot. I use it maybe once or twice per month. I think you would have more customers if it was less expensive.

What do you like best?
I mainly use PDFFiller to fill out and sign forms. The auto-alignment tool for text blocks is very useful. I found the PDF to Word conversion procedure very powerful.
What do you dislike?
The limit in the number of pages and the size of the PDF file often forces me to divide the PDF into several parts before upload.
What problems are you solving with the product? What benefits have you realized?

Great product and even better customer service
I used the product, which was excellent, once during the 30 day trial. However, through my own mistake in not cancelling due to e-mail mix up, I was enrolled in the full year subscription. I explained the situation to support and have been given a full refund. This has to be the best customer service and support I have ever received.

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.
