It will do all the worrying for you. Just install, set up on your phone and let it go to work. Will constantly check itself for battery life and let you know when it needs to be changed.

This is my 2nd purchase of the Google Nest Protect 2nd Generation Smoke and CO2 Detector. It was easy to install and I'm very happy with it.

Bought though when my old smoke detector died. A little expensive, but offers great peace of mind when away from the house. The nest app works well and setup was really easy.

Works well. Added this to a few I already have installed. Only complaint - there are no drywall anchors with the product.

Easy to install Works great! This is the second one we have in our home. The weekly and monthly repots delivered to phone is perfect

This Nest product was a breeze to install and link to the other Nest protector in our house. Using the Nest app make checking the alarms status and testing the operational status at anytime.

These this work great! Love being able to keep track of safety even when away and the night light, while not super bright is helpful.

Great product. Easy to install. I have them at my home and office now

Great detector that you can put anywhere when power isn’t available. Easy to install and connect to WiFi. Good feature that you can interact with your smartphone.

Excellent once installed works as directed all connected and working together in different areas of the house

This is my third detector and would have to say that there is no other smart detector that I would recommend!! If in the market for a smart combo dector, buy this!

Easy to setup and have nice design. After 1 week having it, i got the second one.

Very happy, easily connected to the Nest app, another level of safety! Really like the night light feature.

Since I travel often, I bought this along with Nest Cam's to keep and eye and get alerts if anything is wrong while I am away. The Path lighting feature is pretty good too. Only recommendation would be to go with the 120v model instead of the battery powered if you have a Nest Thermostat so they can "speak" and relay information to each other. The battery model does not do this to conserve power.

While as a unit I like the features and ease of use for these smoke detectors, I HAVE had 2 instances of a "false alarm" for smoke detected since installing this second battery operated unit. The units do link together so while that is a nice feature it makes false alarms worse. So far I would consider it a fluke, but if it occurs again I may lower my rating.

We feel more confortable now at home having this smoke l/carbon detector it’s connected to our network and also work as a night light when you walk by it

I have a fire alarm hardwired into my kitchen ceiling. It goes off every time I make a steak in the oven. I also bought two of these Nest Protect Carbon monoxide/smoke alarms. One is in the front bedroom next to the kitchen, and the other is down the hall in the master bedroom. Now, I get warnings of smoke buildup in the kitchen when I am making something particularly culinary, but the hardwired regular detector stays mum. I like how sensitive these new alarms are, and that I can monitor them from afar.

I am not super techie nor very handy but was able to get this installed, setup, and working properly in about 30 mins. So far everything works great and it is integrated with my iphone

We have been very satisfied with this detector. Monthly sound test ensure everything is in working order. Easy to use and follow on the app.

Tells you what it senses in plain language instead of just an alarm. The alarms are very loud, which is good. Install and setup was easy. Nest is best.
