Fantastic customer service
For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.

Intuitive and easy to use
Easily and quickly fill pdfs with this simple software, just be aware there is no free option other than a 30-day trial.
This software is really straightforward and easy to use. I find it intuitive and am able to edit pdfs quickly and painlessly. Adding a signature is really easy as well.
I did the free trial of this software and even though I was impressed, I didn't end up purchasing the monthly subscription due to my needs. There are options out there that are free, although they're definitely inferior in terms of functionality and user interface. So I think the cost (even though it is reasonable) ended up being not worth it for me specifically in the end. Other than that, I had no problems with the software and would recommend it to someone who uses pdf software frequently.
