    "Love it...I love....The switches that turn the alarm on also require a slightly deft touch, but that is probably part of what you get when you want a clock that does all this does in such a small form factor....I'm going to be honest with you, I had to purchase and return many alarm clocks before because many nowadays have either preset alarm sound meaning that you can't increase or decrease the alarm sound you're waking up to."

    "Love it...Love it!...What can I say, it's a quality alarm, that never fails, and is not expensive Not once has this alarm failed to wake me up, Digits are bright and easy to see If I were to say something negative, The time is a little too fast (in a month you'll notice your like a minute or two ahead of the actual time, easy fix though) And the radio connection needs to better...Just a basic alarm clock needed one to check that my FM transmitter is on the correct frequency one that had a digital tuner fits the bill just fine and a battery back up clock for time announcements ."

    "Love it...Love it!...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....Before an ear-screeching alarm goes off alerting you to how bad a cook you are, the Nest Protect alerts you in a pleasant voice that it has detected smoke and the alarm is about to go off if you don't cancel it."

    "Love it...Love it....The nest gave me a pleasant warning in the form of a woman voice that told me that smoke was detected in the kitchen and that the alarm would sound soon, giving me a chance to hit the button to silence it and then turn up the fan on the rage hood to help clear the smoke....Only 4 stars because they have a shelf life and there is no manufacture date on outside of box, just on alarm itself and you could buy one that's been sitting for a year so you lose a year of life on the alarm."

    "Love it...Must buy...$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....This is a crucial benefit if for even one important point... As this is a dual smoke alarm / carbon monoxide detecter, if your home ever has a CO leak, the Nest Protect tells Nest Thermostat to deactivate the home furnace!"

    "Love It...Love it!...( On each of the motion sensors you can enable an option to ignore motion of things like pets under 40lbs which again is a nice feature) As I say I'd like a halfway house, where I could arm it as 'guarding' and just get a notification rather than sounding the alarm , but its a small gripe when you consider how fully functioned, well thought out and easy to operate this item is....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."
