I can understand their voices not being what they were 40 years ago, but to not take care to record them properly is well, ludicrous... or to be blunt, a major f*** up.

Not specific enough for indoor use, and outdoor range is limited. Also, it doesn't work unless you run the app all the time. Basically, this is the most expensive keychain I've ever bought.
