It’s not as sexy as Google’s Nest, but the First Alert Smoke and C02 detector is among the Wirecutter’s top picks for smoke detectors. I strongly considered picking it up, but did eventually decide on the Nest.
According to CamelCamelCamel this is near an all-time low for pricing. Smoke detectors should be replaced about every 10 years. If you’ve been thinking about replacing yours or realize that you’ve got old ones in your house, this might be a good time to make a purchase.
