Works smoothly and easy to use. Customer support tried to help with a "glitch" I have still not resolved. Works on my iPad perfectly but pull my docs up on desktop just sits there thinking to no end. I've just used on iPad soley since problem came up.

I had some trouble learning to use it and directions aren't consistent. Your Help area tends to be more sales pitch on what can be done in a field with no directions. I'm very grateful for availability of the service though I'll drop it once I have my house sold in a few months

Overall a good experience. Sometimes the lack of features like aligning fields (i.e. Publisher) is frustrating: the ability to copy details from one field to another (drop downs and field attributes) making some forms with several fields that are the same. But I'm an old software designer so I'll take those frustrations and cherish all the good points of the software. I think its a good solution for my needs in the insurance industry.

My experience was good with pdfFiller. I just don't feel that I would use it enough to keep the extra expense! This was my response and I truly liked it a lot but I don't think that I would be using it enough to warrant the extra expense.

PDFFiller I liked being able to create customizable fillable forms for our company. Overall, it is easy to use and responsive. PDF filler is great for a digital signature and saves your previous signature for efficiency. the customizable form feature sometimes lagged and caused minor issues.

Let me start by saying I am an older (58), computer challenged kind of a guy. That said, I have found this program pretty easy to get around. I have been able to take a form my company uses and digitize it so I can actually read the responses people are giving me!! And to be able to store them electronically for future reference.

Great PDF program for mac users I absolutely love pdffiller! I just wish it was either cheaper per month or maybe could be bought for only one or two months when needed.

Easy PDF PDF filler is undoubtedly among the best software I have used for manipulating PDF documents. Easy to use, it offers many features and is less expensive than other software competitors. The only real flaw in my opinion is the lack of clarity about the free trial. The user can modify his document and only when downloading it he is asked to register with a payment method. This can be confusing and irritating if you don't know it beforehand. easy to use accessible from anywhere includes many features there are often problems with payments there is no clarity on the 30-day free trial
