I think this is a wonderful fillable pdf software I've tried, it not only saves your work, but you can print or send to your email. It even gives you the opportunity to fax

The features are great. It would be nice to have the option to combine PDF documents. I also have an issue when entering text where the text box disappears and I have to click on the document again to enter text. Aside from that, he existing features are great and I would like to see how PDFfiller can improve in the future.

Amazing customer service I tried it a while ago, and something went wrong when cancelling my subscription (maybe me...). I got charged for the service anyway, but then asked for a refund. The support team was extremely responsive and useful, I'm really happy about their service. Excellent!
