Books aren’t even reliably great with certain knock offs and or different version/condition substitutions. No Starch Press has had issues With counterfeit printed books. https://www.inc.com/sonya-mann/amazon-counterfeits-no-starch...
This makes it impossible to ascertain anything about the quality and nature of the book you are actually buying - you might read ten reviews complaining about the translation, only none of them are actually about the translation you're looking at - you have no way of knowing unless they happen to mention it in the review you're looking at. You might read many reviews about very poor binding - but is it from the publisher you're looking at? No clue!
This isn't even getting onto the counterfeit issue you mention.
I love my kindle, but translation + kindle is an awful experience.
