Age of Electrotech

TL;DR Buy at your own risk. Read further for why. While I would love to give a better, more in depth product review, I can't. The PDF file is corrupted right out of the box, somehow. I have made several tests to confirm, including changing viewing programs, looking at other PDF documents (which work perfectly), and as a last resort, re-downloading the PDF. None have fixed the problem which is very specific, and crippling. What I know is that it will allow you to open the document and view the first page, but any way you try to scroll down, use bookmarks to skip to a section, or even manually skip to a specific page, crashes my viewing program. It's very unfortunate. From my view of the first page, I can see that the document contains 100 pages of content, and also has bookmarks which outline a very in-depth and probably enjoyable product, but I can't access it. So, I can't in good conscience recommend this product to other buyers, at least not until its fixed.
