It was really easy to use the very first time I used it. It is also cloud based so if I need to use it on a different computer, all I have to do is log in on that computer.

The site is very easy to navigate. I'm a novice when it comes to anything to do with forms, etc. Your site is so easy because it's intuitive. It just makes sense about what to do next, no hunting around trying to figure what the site builders were thinking. Easy peasy.

Kara provided great tech assistance and… Kara provided great tech assistance and she was polite, friendly, knowledgeable, and patient. The 4 stars is for Kara. The company on the other hand... not so helpful. They are great at marketing their product but provide very limited and nearly useless resources for helping their subscribers troubleshoot issues and/or educating the consumer on the tools and functions of the product. The company YouTube channel spends about 30 seconds on "how to" and the remainder of the video is promoting the product. Seriously, every single video, watch for yourself. All fluff and no substance.

I used the *** filler and editing program for about a year. It was great and easy to use on a daily basis! Unfortunately, I no longer need to use this program since I have changed jobs. I was not able to access my account in order to cancel my subscription. But, the customer support team was very responsive and helpful. They helped me cancel my subscription on the same day that I submitted the request. Excellent service! Thank you!

Though you have a great product, I no longer needed it.I had thought I had cancelled before the free trial was up, but, apparently, I had not. So, I asked for help to cancel and get a refund. It was done within a half an hour! Great Service!

What do you like best? Very easy to use. Super helpful. I have to complete so many forms this is an amazing addition so I dont have to hand write everything. What do you dislike? I would say the price, but even that isn't bad. So nothing at all. What problems are you solving with the product? What benefits have you realized? Like mentioned above, I often have so many forms I need to fill out. I love being able to just write and fill in the things I need. To make them look very clean and professional.

Great product and customer service I have been using PDF filler for two years and I am very satisfied with the product. For the first time today, I could not figure something out and sent a question to customer service. Within a very short time I got a response that solved my question. Great customer service.
