This is the second house where we have installed Nest Protect smoke detectors. We have wiring at each smoke detector location, so I purchased the wired model instead of the battery model. I like the integration with other Nest products, such as the Nest Smart Thermostat, into their phone app. I also like the compatibility with my smart home system. These detectors are more expensive than other brands, but I value the safety features, voice announcements, and the built-in nightlight that activates when it detects motion at night.
