Not Sensitive Enough To Smell of Smoke
I tested this smoke alarm by placing it several feet above a small fire. Only after about a minute or two, COMPLETELY ENSHROUDED IN SMOKE, did the alarm sound, and for ONLY 3 BLASTS. It should have sounded off at just the smell of smoke, and for maybe 6 or 8 blasts. I have been in motels where the smoke alarm went off repeatedly after just turning on the heater when no smoke was produced. The smoke alarm went off because it merely sensed the smell of something burnt or about to burn as when the heater coil starts to get extremely hot when heated by an electric current. This smoke detector is better than nothing, but barely. Spend a few more bucks and get a commercial grade smoke detector like the motels have.
