    "Love it...Love it!...This is my second nest protect....I feel very secure with nest products....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...Love it!...I love the nest home security system....As a whole it is a pretty neat system and while I am still unsure about placing me in control of the monitoring aspect it certainly beats needing a security permit (which IS required where I live), having the cops standing at my house when I arrive to only discover it was a false alarm, or paying the monthly fee for having someone else handling the monitoring."

    "Love it...I love....I did turn it on briefly when I first got the alarm clock - I don't remember being either impressed or annoyed by it - I think it is probably what you would expect in a little bedside clock radio - nothing to right home about, and you're probably not going to want to blast it while you're getting ready in the morning, but it is probably fine to wake up to....The two alarms are great, one for every day and one I can change for specific occasions or as I currently have it a backup alarm I can quickly turn on when I want something more than snooze."
