    Apparently when my house was built, the wiring for the smoke detector was placed in the hallway next to the bathroom. Nearly every time somebody goes in there to take a shower the steam from the bathroom sets off the smoke detector. I wish that I had a way to move the wiring without having to hire an electrician! They really need to set an option in the app to turn down the sensitivity.

    Nice that it is compatible with existing nest smoke detectors. Like the interconnected aspect. Didnt realize hoe many features nest originally had i.e. night light, interconnected without red wire. These dont check every box, but most.

    Missing nest protect features, poor sound quality

    I'm sure this smoke and CO detector works well enough for it's intended safety purposes but as far as it being marketed as a Nest Protect replacement it's missing some of the convenience features that were on the Protect due to the lack of a motion sensor. I really miss the path light feature. Also the speaker on this pales on comparison to the Protect. Also it requires another app and account in addition to the google home account.

    Fairly easy to replace the Nest sensor we had with the included adapter in the First Alert packaging. Seems to work fine but did have to download and set up an additional app - not a big deal.

    East to replace the Nest Detector with this model. Only issue is that it tends to drop off my WIFI from time to time, and it’s near the access point. Other than that, seems to work great.

    I was disappointed when google decided to discontinue the Nest Protect. This fit the bill for me as it works with my other nest protects that havent expired and is aesthetically pleasing to me on the ceiling. So far so good!
