Bests & Worsts Reviews from Amazon

I literally kissed my fire alarm this morning. Bought this two months ago to put in my detached building that houses my exotic birds. This morning the heater started to smoke and this alarm detected it IMMEDIATELY! The alarm woke me up (through the baby monitor) and I ran outside barefoot! Luckily, the building didn't even have time to fill with smoke, and you could only smell the smoke on the heater. This fire alarm saved my building and most importantly it saved my beloved birds!! Birds are incredibly sensitive to smoke, so the fact that this thing was able to detect the problem so soon is INCREDIBLE. The alarm was positioned about 5 feet almost directly above the heater. I highly recommend!!!
