This is a good scan of the product. The text is clear, and I cannot see any evidence of anti-aliasing or blurring of the letters when zoomed in. These two PDFs work fine on my old, underpowered tablet, zoomed in on my phone, and on my Kindle (not all PDFs sold here load quickly and work properly on these three devices). The bookmarks are well done.
