@Edent I'm gonna play devil's advocate here. What's wrong with that review? They liked it 4/5, and their comment is that they had better expectations from what they read on the paper, which admittedly is not a lot of info, but it's still an opinion.
Or is the problem with "Four Stars" in the subject line?
My absolute favorite "license required" experience on Amazon is when people answer customer questions with "no idea, sorry". I always suspected that they are prompted to answer somehow.
