    Customer review by jillyc

    I have this in my home. Lastnite it started going off. I had never heard one go off before. I got my kids and pets out of the house and called the fire department. They arrived and found that my house was at 50% full of carbon monoxide where my water heater is at. The water heater was the source of the problem. If it was not for this alarm my children and I would not be here today. This alarm SAVED our lives. I am going to invest in one of these for each room of my house.

    The CO monitor is reasonably priced and is made by a well known company. I purchased one for each floor of the house including the basement
