Review title: PITA
Product review: Our house is only three years old. In the past two weeks, one by one a detector is going off alerting "CO Move to Fresh Air". Every time it happens, I have one poor dog who pees on the floor. I have tested batteries, opened windows, etc. I finally had the furnace guy out. He could not find any trace of CO. Apparently these things were not meant to last. So far four detectors have done this. I am grateful that all four went off during the day! That is the only good news about these.
