Customer Ratings & Reviews

We purchased 5 Nest Protects to replace our old smoke detectors - which had reached the end of their 10-year usable life - because of three key features: integrated CO2 detection (to get rid of the separate, ugly plug-in detectors); the more subtle voice alerting with instructions (rather than the immediate and jarring shrieking that our old detectors would do if the kitchen got a little smoky); ability to control from the same app as our several Nest Thermostats. HOWEVER we had to return all the Nest Protects because they were missing one critical feature: compatibility with our home security system. This meant that the fire department would NOT be automatically alerted in case of fire. This would not be a major issue if we were at home in the unlikely event of fire, as we could call the fire department from our cell phones on the way out of the house. But if we were out of the house or away on vacation, the fire department would only learn of fire AFTER a neighbor or passerby took notice and called it in... and by the time fire was that noticeable, how far would the fire have progressed? How much of the house would already be destroyed? Most importantly, what chances would our pets have of being saved? While such an event is unlikely, it was not a risk we were willing to take, But we really wanted to keep the Nest Protects, so looked for security systems compatible with them, willing to replace the one that had been installed by the previous owners of our home, in order to use th Nest Protects. So I searched the 'works with nest' section of their web site and found that Nest Protect is not compatible with ANY home security systems with central monitoring (ADT Pulse appears to be compatible with Nest thermostats, but require using public their own proprietary smoke/CO2 detectors). The only compatible security systems were a couple of startups (one still in Kickstarter stage) that had Wi-Fi enabled DIY systems that worked like a Sonos audio system, allowing owners to install detectors, cameras, etc. where they please. But I was not willing to trust my family's safety and all our belongings to a company that could be gone by the time I press 'publish' on this review. Bottom line: Nest Connect is a very cool product, probably good for people in apartments where building alarms or neighbors would quickly notice smoke or fire if no one were home. We ended up buying traditional smoke detectors with integrated CO2 (so we can still get rid of the plug-in units). We look forward to considering Nest again, when the 10-year life on our new detectors is past. Hope by then Nest can integrate with central alarm monitoring services.

Happy with my nest I like that it notifies me on my phone if something is wrong

Great alarm. Dual spectrum smoke detection plus CO detection. Excellent WiFi integration with the Nest system.

having kids makes this device fantastic...does daily check , & will alert if anything is above tolerance

Excellent product for the money. Combined smoke and carbon detector in one product.

Great smoke sensor. The best I found. Integrates well with other smoker detectors in the house

Product was easy to setup and even easier to mount on the wall. Highly recommend as a single solution for your home.

Easy to set up and install. Information and status of the alarms is readily provided, rather than waiting for an alarm to sound.

Great product. 2nd one. Will be buying more. It's great that you can get notifications and see if everything is ok at home.

We purchased for our 2nd home and has give peace of mind like the one we have in our main home.

I have owned two Nest smoke alarms for approximately three years. One malfunctioned and cannot be repaired. Not an impressive performance for an expensive unit. I was reluctant but purchased three more Nest smoke alarms. I'm hoping for the best.

Like the path light. Can check it via the nest app. Be forewarned that you must change all fire alarms. By code cannot mix and match. Can become an expensive project.

my last one lasted 5 years so a little disappointed. Love the nest detectors.

Can’t go wrong with nest products. Easy to install

Nest is always a great product. It does not disappoint. Buy with confidence.

It works as advertised and provides an extra sense of security. Particularly useful when paired with other Nest products.

I replaced my outdated detectors with these. Now with both smoke and carbon monoxide detection, I can sleep again.

Great product !! no more beeping noise at night when the battery get low from cheaper smoke & fire detectors.

We like the versatility of the best protect. Being able to check our home from anywhere gives us peace of mind

when it comes to safety, you should never take a short cut. go for the best reguardless of cost.
