"All smoke detectors start to degrade after five years, and by year ten, you just can't trust them anymore with your and your family's safety. Six or seven years is best; eight is okay, but anything more than eight is far too risky."

"These things are apparently programmed from the factory to go off only in the middle of the night. It's like some torture game of hide and seek. By the time you figure out which one is malfunctioning, you've been awake and annoyed long enough that you're pretty much now wide awake. I've lost enough sleep on random nights over the past several weeks that I'm just going to replace all the rest of the ones in my house and just move on with my life."

" I purchased a new construction home in 2012 and these were installed by the builder. I am a gadget guy and received a Nest Aware for a gift last year and loved it. Yes, I could easily replace the First Alert every 5 years and save the money, but the hassle is not worth it. The Nest is a far superior product."
