This is the first time I've needed this type of aid, and I've found it to be very useful and relatively easy to use. Sorry, I'm really too swamped with work to do another survey

Everything has been great, with the exception that it takes a while to open up the documents on mybox. There should be a feature for ''QUICKVIEW" of the document you want to open.

It was the worst because I had no idea how to work the program. It took well over 5hrs for something that should have taken less than 5 mins had a I known what to do

Love it- so easy- wish there was a cheaper option for "stay at home moms" (could verify with a phone call) - since all I tend to use it for is school forms and household paperwork

Easy to use I couldn't do my job without this tool. I utilized this everyday as I create and fill out forms quite often. Its very simple and does not take any time to understand how to utilize the software. At times it can give you problems when you try and save and add certain things. I've also had problems copy certain areas.

Kara, The Support Agent The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.

Best customer service ever Best customer service ever! I accidentally signed for a year and it cost me an amount of money I can't afford (it doesn't seem much, but when your local currency is way behind USD, it greatly hurts your wallet). After reaching Rachel on pdfFiller's customer service team, they not only refunded me but also waived a month of free access. I couldn't be happier of using it! Recommending it to all my friends, from now on!

I'm a college professor that has to use this pdf editor for both class content and administrative content. It's fine. Not as good as adobe but it is cheaper.
