In our apartments we are required by law to have “SMOKE DETECTORS” hanging on the wall. I’ve had gatherings in my house where the air has been so thick with cigarette smoke you need a knife to cut through it. The smoke detector sits silent through the whole event. If you boil a pot of water on the stove or have a shower with the door open the ****ing thing goes ballistic! What kind of mutant technology is this and why am I required by law to put up with its ill conceived design? Some days I swear I’d rather burn to death than tolerate more senseless racket from this poor misguided piece of electronic Hoo Haa! I’ve lived in a lot of apartments in my life, and these ****ers never, ever work….Ever!!! If the powers that be are requiring me to have this water vapor sniffer/ smoke detector in my home then I want one that work DAMNED IT!
