Not 24 hours after the aquisition, I ran the siren up to the first time in my ownership, and it sounds very nice for its age! Also, this will hopefully be the last video with the camera microphone, as I just recieved a new one (this would have been the first, if I was smart and turn the mic on...
Enjoy!
