FYI, along with the 'name' change / rebranding to PDF Elements, the price jumped to $99.95.
I tried out the PDF Elements version 5.7.1 (as of Feb 2017) trial version for giggles. Found it extremely slow in file operations. I'm not a big fan of ANY of the PDF apps for Mac, I keep trying them, hoping one day one will be actually bring some competition to Acrobat. If you are on a budget and can't afford Acrobat, of all the others I've tried so far, PDFPenPro is adequate, and costs $125. If you are considering this PDF Elements at $99, you probably should think hard about spending another $25 and getting PDFPEnPro. The main feature you will gain is ability to insert pictures (like a signature) and also true digital signatures certificates.
