When the alarm is triggered, it turns the empeg on and plays "Help! I'm being stolen" repetitively at ear-drum splitting levels, or alternatively plays 'I should be so lucky' by Kylie Minogue, at said levels, which should be enough to drive the would-be thief insane.

I love it. But does it only play "I'm being stolen" until it is pulled from the sled?


Unfortunately, yes. But that is tempered by the fact that everytime the thief attempts to get it out of the sled he gets a very nasty electrical shock
In fact with all these pain technologies, the empeg is cypto-locked into the sled just to make it's removal more painful.
