Rated 5 out of 5 by from Product review Nest Protect I've had a Nest Protect installed for a couple of months. It replaced a wired smoke detector. The features offered are worth paying a little more for, particularly the CO2 detection feature. The setup via the app was easy and allows access to operational information from anywhere. Also, the monthly test feature/push notification, night light with multiple functions, connectable to multiple Nest Protect feature and battery backup feature put this device ahead of the traditional smoke detector. I place a high value on home safety and I plan to upgrade the remaining detectors in my home.

Rated 5 out of 5 by from a piece of mind I have been updating my home to a smart-home and never thought about a smoke detector till my old one started beeping... so i stopped out and got a nest protect. its a smoke detector soooo there's not a ton to say about it because i don't have fires very often in my home! but it does a monthly test (its also loud) and sends me notifications letting me know every thing i working well. And to be honest that is a big selling point, to find out i need a new battery while i'm out and about as opposed to when i'm trying to sleep... and i like knowing if i did have a fire id know well before arriving home to find out!!!

Rated 5 out of 5 by from Easy Peazy Set-Up We were originally only replacing the CO detector until we saw Nest Protect. We already have Nest thermostat and are thrilled. We loved the idea of getting notified in the event of a fire or CO incident bc we have a teen who just started staying home alone. We also have pets, so it makes us feel better knowing they too are home safe. It was an easy decision to buy. Install was easy! Great follow along instructions. The ONLY problem we encountered was the screws provided were too short but we used old ones just fine. Otherwise install was literally 10 minutes or less.

Rated 5 out of 5 by from Great Products Upgrading my two old thermostats to the nest (3rd generation) was one of the best investment I have done around the house. I now have also installed a Nest Protect Smoke detector and it worked like a charm. It is so easy to set up and control from both, the unit and the application. I love the Home/Away feauture that allows the Nests to go into eco temperature move to save energy when there's nobody at home without getting the house too cold in winter or too hot in summer The voice alerts from the smoke detector have an additional awaking and effect in my kids
