    First Alert Smoke and Fire Detector

    Customer review by SAGuy

    5.0 stars by SAGuy

    a friend recommended we get photoelectric smoke detectors (our home has the Ion type of detectors). The First Alert is a great product. A great feature is a bright light the comes on when the alarm sounds an alert. That would make it much easier to see in the middle of the night if we ever have a fire.
