Bests & Worsts Reviews from Amazon

These alarms were installed in a brand new construction home. They were paired with BRK/First Alert Photoelectric smoke alarms for a total of 11 units. They were super easy to install and worked silently...for about 2 weeks. First, the alarms would randomly chirp 3 times once or twice per day. Then they started going off for no reason. Now I don't know if you've ever been sleeping in a home when 11 different smoke alarms/ carbon monoxide detectors go off, but I wouldn't recommend it! It's not fun! The alarms would sound for about 15 seconds and then stop so we did t even have time to run around and figure out which alarm was causing all the ruckus. Today the alarms went off again but this time they didn't stop. I ran around hitting silence buttons but they still didn't stop. None of the alarms was showing that it was the culprit and none of the silence buttons worked. After 5 LOOOOOONG minutes of screaming and running around frantically trying to stop the madness, we started to yank the alarms off the ceiling. I was livid!!!! I called First Alert and they offered to send me ONE replacement unit but it was up to me to decide which one had malfunctioned. Then I asked how to silence them the next time this happens since the buttons didn't work. I was told to get on a ladder with a hair dryer on the cool setting and blow air into each and every smoke alarm until they stop. REALLY????????? You want me to do that at 3:30 in the morning when I'm trying to decide if I need to evacuate my family or if it's just cheaply built smoke alarms creating a false alarm???? That's the protocol for unusable smoke alarms? Do yourself a favor and avoid First Alert like the plague. I'm currently shopping for new smoke alarms....after less that a month of usage in my brand new home. I just don't trust them to work when/if I truly have a disastourous situation in my home.
