Sometimes it is hard to figure out the forms. I thought once I type in one form, that the information would replicate into the forms below, but that didn't happen.

The only thing I wished for in using it was copy/paste for adding many text lines of the same size and shape again and again instead of creating each one each time.

My need for a Blumberg standard lease was satisfied, however the number of typographical errors in the form were surprising and correcting them caused a change in the font!! Very frustrating!

Use PDFfiller for my PDF editing and signing needs I use it quite often and it has made my life much easier. PDFfiller provides a lot of functionality for a low cost compared to other solutions. A few features were missing when I first started using it but they have added functionality and it's much better now.

It took a while to get used to and I had to have several chats with tech support over several weeks. I subscribed, but I still ended up with a free account that I had to get them to delete. I had to check my login box to ensure I was in my subscription account.

experience At first it seemed hard, trying to figure out how to save the completed document, and to get to the next step of saving the document and sending it by email. But I got it now. Thanks

IT IS SUPER EASY RIGHT OUT OF THE GATE. I AM NOT SURE HOW TO FIND A DIFFERENT IRS FORM. I AM THINKING MY ADOBE DC MAY DO THIS AND I JUST DON'T KNOW IT. I FOUND THIS ON THE INTERNET AND IT IS SAVING ME HOURS.

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.
