"Very difficult to hear"
The content of this is probably better read and studied next to other Jonathan Swift works. The quality of the recording is very poor. I suggest you read it.
"Very good reading; subpar audio quality"
Obviously this is a great story, a masterpiece of satirical humor. I am not reviewing the story. I just wanted to note that I thought the reading performance was very good. The audio quality is not so great, but I found it totally listenable and enjoyed it.
"waste of money"
As been said, this is very difficult to hear; it's the worst audio quality of anything I've ever got from audible.
On top of that, the reader (firmly American) reads without any of the drama and irony that might help to communicate the point of Swift's satire.
Doing these kinds of texts badly is a sadly wasted opportunity.
