Kudos to the makers of the carbon monoxide alarm in my house.  It was a SUPER design idea to have it beep EVERY THIRTY FUCKING SECONDS when it is on low battery,  Nothing better than a "chirp" noise twice a minute waking you up (and not letting you get back to sleep) at 3:00AM.
Awesome. I feel fresh as a daisy dappled with morning dew.
