I was actually unsure whether to buy this or not, as I was worried that, being recorded at a real theatrical performance, the lack of any kind of description of the scenes and actions would make it difficult to follow, and consequently render it less enjoyable.
I had no reason to worry. The quality of the sound is very good, and the actors are really great, so you can recognize the different characters with no problem. And fortunately the conversations alone let you easily understand where the action is taking place and what is happening.
As for the rest, there is very little to say:
I won't even try to review the story, it's just too great (and witty, and silly, and funny, and brilliant, and a lot of other similar adjectives) for words.
The quality of the sound is very good.
The actors impersonate the various characters perfectly, and hearing this play actually acted out is infinitely better than just reading it (after all, this is the way it was meant to be enjoyed). I already knew the story well (it's one of my favorite books) but hearing it this way still made me laugh out loud!!!
