So far so good! Can't figure out a way to fill in dates properly though without dragging text in - or change the check box from cross to tick. Overall though saving a lot of time!

I absolutely love, PDF filler. It is so easy to create forms whether I use them as fillable or not, they are terrific. I love that I can name each form and save each form. It's so easy to print my new forms. I'm actually having the time of my life creating them, it's actually fun I know no one else is probably going to say that but I think it's really fun to use. I am 59 years old and this is better than Etch-a-Sketch back in the day and that says a lot lol I would highly recommend pdfFiller to anyone and I have. I own 3 medical practices and we have forms forms and more forms. PDF filler has been just an absolute lifesaver. I've also use it for personal forms that I need. I haven't had a need to use any of the pre templates that are available. I'm just so thrilled that I found pdfFiller. I actually purchased two Remarkable tablets for my practice and that was a disaster. It was an unremarkable purchase to say the least. It's just not that great when it comes to creating a beautiful document, it just wasn't for us. So glad that I went on Google and found pdfFiller. I am happy business owner!
Thank you.

I have trouble using the pdffiller on my laptop, I can not upload b/c the screen is not wide enough to get to the click button. I can on my desktop when I go into the office. Sometimes the app does not give me the ability to save or download - I have to play with it back in forth before it will save as a fillable file. But my biggest issue is using my laptop when I work remotely and I have to use it. Thanks for inquiry and the survey to give me the opportunity to voice a concern.

Working great for filling out forms
Working great for filling out forms, on my phone or PC saving and printing. However, trouble signing in when opening file from email and works more smoothly if signed in before opening.

What do you like best?
Everything about PDFFiller makes my days easier. It's affordable, easy to use, and makes any PDF editing absolutely easy and fast. I would definitely recommend PDFFiller to anyone who needs to be able to edit PDFs or make them fillable. Hands down the best program I've ever used!
What do you dislike?
I haven't found anything about PDFFiller yet that isn't helpful or user friendly.
Recommendations to others considering the product:
If you need a software that does it all - edits PDF files, helps you to make PDF files fillable, even lets you send out faxes - PDF Filler is what you need! The annual cost is very affordable for all that it offers and I've yet to see, use, or even hear about any other service that offers all that PDFFiiller does.
What problems are you solving with the product? What benefits have you realized?
The problems that I solve using PDFFiller most is to make PDFs fillable - especially since COVID started and we have more people working from home or trying to fill out documents from home.
