Review on X-Sense SD01 10-Year Battery Smoke Detector with Escape Light - UL 217 Compliant (Not Hardwired) by Michael Wilson

Easy to install and good looking. Rescue light adds more sense of security. This should be very helpful in poor visibility. The sound of the alarm clock is pretty modest compared to the old one I had that woke up all the neighbors in the same house. You may miss this when you are sound asleep and the alarm clock rings outside the bedroom. Because of this, I recommend having one for each bedroom. You should also avoid installing it near bathrooms, humidifiers, or dryers that emit humid air, as extreme humidity will set off an alarm. I have it 10 feet from the bathroom, but if I take a long shower with the door open (though I don't think many people do) it activates. Otherwise I don't have any big problems. Looks better than the ones I've seen in CVS for the same price. Goodbye.
