Nothing Particular other than finding out the particular IRS forms I expected to print from the IRS wasn't acceptable to download and print, and I had to purchase them when you advertise free IRS forms.

I loved using the program. It helped on saving paper while allowing to update documents without having to print, use white out, and scan the updated document. It was really the only feature I used, but i know there was so much more to the program. I would love if they created a pay option that was cheaper than basic or reduced the price of basic for those of us who just need it for one or two functions. It was very easy to use and i wish i needed it for other things. Overall still a great program and i would recommend it to anyone. I am only giving it 4 stars due to me just not needing it for a whole lot.

Initially was not happy for being charged £150 after my free trial ended (without knowing) though they processed my refund very quickly.

Awesome PDF Tool for a low price
It is a great tool that I would recommend to people who are not very tech savvy.
It is an easy to use tool with helpful features that can help any business that uses PDF documents on a frequent basis.
It makes you pay for many features that can actually be found using free software alternatives if you do some research.

Perfect for College
I've been using this for my online math course worksheets and this has been so helpful. It's easy to type and draw, editing isn't annoying, and the color palate is easy on the eyes.
