    A much better upgrade from version one. Easy to set up wired since it’s low voltage. Version one would have the tendency to freak out and go off. This version has had no false alarms.

    This is a great piece of kit. So much so that I am going to use them throughout my house, so I will be purchasing ten of them! They are smart and efficient. My wife who is fond of burning food is happy as it won't set off the sensor and we are all happy my son can find the toilet at night!

    This is so much better than the traditional smoke/carbon monoxide alarms. It sends an alert to my phone if there's smoke, so even if I'm not home I can protect my house. It takes a moment to set it up, but it's well worth it.

    I bought 2 battery and 2 wired versions to replace older ones in my home and love the features so far. It's nice to hear a voice response instead of just a horn sound. Also I love every how it integrates with the whole home automation program. Worth the money so far.

    tired of the 'old' smoke alarm going off everytime the oven was used... no we were not constantly burning stuff! Interested in the Nest because of the ability to turn alarm off from phone app. Happy to say have not even needed to turn off via the app. Oven has never set the Nest off.

    I never expected to think that a smart smoke/carbon monoxide detector would be a worthwhile purchase but Google has proven me wrong

    1st smoke/carbon monoxide detector I purchase. Although a bit pricy it's worth it. Smoke detection works well and the App offers many options for monitoring its status.

    I like the smoke detector you do not get a lot of false alarms, Low battery alert etc. although it does warn you when your batteries are low and these are relatively easy to change however I had one fail before its life expectancy and nest made it right but in my opinion they (nest)Should have a warranty that ends at the end of their life expectancy typed on the back,You pay a lot of money for these and the warrantee should back it up

    I really love these smoke detectors. One of my favorite features is the path lighting, it illuminates the hallway leading to my restroom and kitchen area. I also enjoy the instant alerts to my mobile devise when alarms are triggered due to smoke or carbon monoxide detection.

    Love that it is a combined smoke and CO2 alarm. Inadvertently tested with a steak that got smoky and it was impressive with the alerts on my phone, being able to suppress the alarm, and notification of the smoke clearing. Extra bonus is the motion detector night light.

    Picked up 3 wired and 1 wireless model. Very easy to install, replaced old yellowed smoke detectors from 1987! Always know when grandma burns the food as I get a notification (via nest app) that smoke is detected!

    Straight up.. These are NOT cheap but if you have animals and are sick and tired of those annoying as **** chirps and loud beeps that alone makes these worth it. The advance warnings, lighting of pathways, soothing VOICE warnings, EZ set up... BAM... Awesome.

    I already had a Nest thermostat so I was familiar with how well their products work. I like having the new smoke and carbon monoxide detector that can be controlled via my phone. I recommend this product to anyone wanting to upgrade their smart home environment.
