I have to tell my dr. to use this. Tired of his hand-printed & copied over & over stuff & can fax it immediately since he snail mails everything. Highly recommend to anyone who can use all the features. Added plus is that it's so easy to use. It eliminates paper, toner and postage and well worth the price for anyone who needs all the bells & whistles (which he does!!). Thank you, PDFfiller !!

I signed up for the $1 trial but did not want the 1 year subscription -- refunded in two days! I signed up for the $1 trial but did not use it for whatever reason. I have adobe DCF but used PDF filler one time to check it out or whatever. In any case, one month later I get hit with the $102.10 one year subscription charge I didn't see coming. I call expecting to be on hold for two hours.. but .. no... about a few minutes on hold and they refunded the whole thing.. refund hit in two days. So, I believe they should be applauded for that. I'm sure some people love it and go for the subscription. But it's really nice to know they're actually honest and refund the money if you ask.
