Review title: dead in 11 months
Product review: I bought 4 of these. At about ten months after buying them, I went to install the last battery into the smoke detector. The battery was dead in the package. I tested the other smoke detectors. One other battery was dead. Two months later, a third detector started chirping. In eleven months, three out of four were dead.
