    "Love it...And wow!...I bought the battery one because this is an old house and I don't have power available close by....The Nest smoke detector was easy to install and works great about a week after installing the detector I got a alert on my phone that it had gone off while at work my daughter was home so I immediately called home to see what the issue was and she advised that some food was left unattended and was burning and smoking a lot but everything was ok a few minutes later got another alert that smoke was clearing and all was ok."

    "Love It...So cool....Great but prefer the battery one...$99 may seem like a lot to pay for a smoke/CO alarm, but considering that in CA, you're now required to have a combo smoke/CO *with a sealed lithium battery* in every room, and the generic brands that are up to code cost $60 or more, the Nest Protect is really the way to go."
