Our tester reported that this alarm "is smart enough to distinguish real smoke from shower steam or minor cooking smoke." When compared with two other models he tested, the Nest Protect was the only device that didn't sound as a result of cooking-despite being "mounted right next to one of the offending alarms." The built-in carbon monoxide (CO) detector is similarly accurate and lasts 10 years. The Nest Protect even features advanced technology in terms of smoke detection, combining the strengths of photoelectric and ionization sensors into a split-spectrum sensor that better detects both smoldering and flaming fires, in addition to greatly reducing false alarms. The devices quickly connected to the Wi-Fi network and the Nest app, where heads-up smoke alerts come through and can be dismissed before the full, very loud alarm goes off.

As a testament to the easy setup process, our reviewer was able to install two battery-powered Nest Protect units (hardwired installation is an option as well) in the span of 20 minutes.

Despite the high price tag, our tester gave it a full 5 out of 5 stars for its combination of quality and user-friendliness.

The Google Nest Protect is a pioneering smart smoke detector that, in its second iteration, remains at the top of the market. The Nest Protect Smoke and Carbon Monoxide Alarm Is Smart and User-friendly
