Title: Will not Save your life...doesn't work
Product review: I have a newer Knighthawk and a very old plugin carbon monoxide detector. We had high winds and power went off last night. When the power came on my old unit sounded the alarm. I took it downstairs where furnace, water heater and Knighthawk were. Knighthawk was registering 0, ppm. Older unit sounded alarm when I plugged it in. I could smell gas from water heater, the pilot had blown out. Shutdown gas and aired out house, old unit quit sounding the alarm once the house was aired out.This is scary, if the power had not come on the Knighthawk with it battery backup would never have sounded the alert and I might have died. There should be a way to test these alarms accuracy, pushing a test button does nothing. Does anyone know of Carbon Monoxide alarm that is not made in CHINA?
