I found it to be very useful but expensive. I wish I would've had the option of paying monthly instead of a one time upfront transaction with no warning.

I like how easy it is to take a PDF and be able to type what I need to, change colors and fonts

I wish that the erase tool would be able to go in different directions, not just left and right but to be able to use it more freely to erase easier.
What problems are you solving with the product? What benefits have you realized?
benefit in using this for my business is keeping documents clean and not having to print them out hand write on them scan them back in and email it, I can do it all in PDFfiller and keeps my documents clean, and is a lot easier.

Add an equation with LaTeX or Math ML in the toolbar, then choose Equation. You can also choose Insert > Equation (from the Insert menu at the top of your screen). If you have Datatype installed, a dialog appears, asking whether to use Pages to create the equation. Click Use Pages.
Pages does not have an equation editor by default. Apple does say, however, that if you have Datatype 6 installed, you can use that from within Pages, and equations are then treated as graphics. One option is to install a Latex distribution like Mac Tex and then use a small software called Latex It.
You can also choose Insert > Equation (from the Insert menu at the top of your screen). If you have Datatype installed, a dialog appears, asking whether to use Pages to create the equation. Click Use Pages. Enter an equation in the field using LaTeX commands or Math ML elements.
Do one of the following: Tap, tap. Enter a LaTeX or Math ML equation using the keyboard and the math symbols above the keyboard. Tap Insert.
Click in the toolbar, then in the Basic category, click a line. Options include a straight line with or without endpoints, or a line with editing points to create a curved line. Click to select an existing line on a page.
Go to Insert — Symbol. Scroll down until you see Symbol. Look for the Division sign. Click on the Division symbol. The Division symbol will now appear on the page.
On the Mac, there are a few keyboard shortcuts by pressing and holding the Option/Alt key () whilst pressing another character on the keyboard. Or a combination of the Option/Alt key and the Shift key (). For example, the division symbol (÷) is and /.
