Review title: Warning! Warning! Warning!
Product review: If you buy this product be prepared to be awakened repeatedly in the middle of the night by the unit going off screaming "Fire!, Fire! Firer!" and blaring its alarm for no reason. This unit was installed by electrician and is not near a fuel burning appliance or exposed to any other condition that would cause false alarms. It is only 7 months old. Also had problems with it being too sensitive when first got it. None of the other units (plain smoke detectors) go off with it or ever have, and we have never experienced this with any prior smoke detectors or CO detectors. And it only happens in the middle of the night. Had to disconnect.
