The story seems to have several variants: Beginner or inexperienced player writes on a discussion board that they didn’t want to buy a Generation because of the dangers of flaws, or had read about bad quality control of Generation whistles so they didn’t buy one. Beginner or inexperienced player buys a Generation whistle and cannot immediately play all the notes correctly, cannot immediately get all the second octave notes, and/or plays it into tuner and decides that it’s “out of tune” … then they go online, read some other comment about “bad Generations” and declare that theirs is also a “bad Generation”.
