Customer Ratings & Reviews

I was sick of not being able to reach my old smoke alarms that would seemingly go off without warning. Already own a nest thermostat do this was a no brainer. Easy to install and use

Best smoke detector I have found. The path light (wired version) is a really cool feature. Two year battery life is great with the ability to see the battery's health. No more annoying chirps in the middle of the night because a battery is dead.

Purchased 6 of these hard wired Nest smoke detectors. Love how easy it is to install and how it works seamlessly with the other Nest products. Highly recommend these!

This is a great device. Fully configurable, easy to use and all alerts show up on your phone. Alerts come in degrees so you can have a “heads up” vs an “emergency”.

This is a great smoke detector. Easy to install and works perfectly while testing. Hopefully I won’t have to ever use it.

Great product easy to install connect it right to my nest app. no more false alarms when I cook very good quality product.

Mine was a replacement for a wired smoke detector so the wiring and installation was easy. Shut off power, remove old detector and wiring connector, insert new wiring connector and mount new Nest unit base and twist the unit onto the base, turn on power. Installation was less than 20 minutes. Only issue is that Nest doesn't support windows phone.

Easy install, easy setup. Great product to add a connected smoke alarm system without wires

AWESOME QUALITY PRODUCT. easy to use, well made and controlled by an app

Great addition to our smart home. It was easy to install with the detailed instructions. Will need knowledge to hardwire.

A high tech smoke detector for both smoke and carbon monoxide detection. Love that it works with wifi and has a voice response and don't have to worry about changing batteries.

This is a pretty nice smoke detector and CO2 detector. If you have other Nest produtcts, then this is a good purchase because it will interact with the Nest thermostat to turn it off if it detects CO2 as well as helping the Nest thermostat learn when someone is home for advanced heating/cooling schedules. I gave this a 3 star review because I can’t believe the thermostat doesn’t have the connectivity wire that links it in with the rest of the non-Nest fire alarms in your house. So, if this fire alarm goes off, it will not trigger the other non-Nest fire alarms in the house as well. If you have multiple Nest Protect units, then they will talk to each other and alarm, but that’s not good enough in my opinion. It’s a way to get you to buy multiple Nest Protects and that is kinda lame in my opinion. Installation was super easy, software setup is very intuitive.

Easy to set up. Feel safe knowing if there is a problem and I am away. The only bad thing is it cannot be connected in series (other alarms cannot set it off if they are activated)

The Nest Smoke/CO2 detector is a great option for new installations or retros. Easy to install and setup.

I really like the Nest Protect so far. Easy to set up, easy to access through the app, and notifies you of any events in your house.

The detectors are very "smart", and linked well to each other. Very good installation instructions. Unfortunately, I erroneously believed that they would data-link with the Nest burglar/intrusion alarm central unit. This is not the case, so whereas the intrusion alarms can send notifications to the Brinks security center, the CO/smoke/fire detection units are only useful to notify those physically present to either check out the system sensors or evacuate - providing no benefit whatsoever when residents are away. This is ironic, considering the sophistication of the software in the units - perhaps someday there'll be a software upgrade which will permit the units to link to the central alarm system. The wireless link permits installation without requiring a third wire, and battery units will also link up, if your house is not hard-wired for detectors or linking third wires. The soft light which lights as you approach the area beneath the unit is an excellent night light. Overall, an excellent system, albeit rather pricey, but do not look for this to notify a call center or lower your insurance costs.

This was really easy to install. I like the automated testing and health check each day. It's one of those things you hope you never need to use...but you're glad I have it.

Great product I have used them for years now love that it’s connected to WiFi and sends instant messages in case of smoke. Great product.

Installation was easy. It is the same like other home automation items and internet connected devices. You can always use a mobile app to control them.

Placed these in strategic places near furnaces and living spaces. Love the built in motion sensor that turns on a light on the unit to light the way for kids at night.
