Rated 5 out of 5 by from Easy Peazy Set-Up We were originally only replacing the CO detector until we saw Nest Protect. We already have Nest thermostat and are thrilled. We loved the idea of getting notified in the event of a fire or CO incident bc we have a teen who just started staying home alone. We also have pets, so it makes us feel better knowing they too are home safe. It was an easy decision to buy. Install was easy! Great follow along instructions. The ONLY problem we encountered was the screws provided were too short but we used old ones just fine. Otherwise install was literally 10 minutes or less.

Rated 5 out of 5 by from Great All Around Product This product does not disappoint and is ascetically pleasing as it is functional. Yes, the price is alittle high for a smoke/co2 detector but the functions it offers, ease of installation and setup, and the comfort that knowing wherever you are at that you will be alerted. The setup and installation took no more than 5 minutes, but at most I think the setup would take 15 mins for a battery one which I have. We have other nest devices in our home and having them all connected and being monitored on one app is awesome, let alone easy to control and monitor.

Rated 5 out of 5 by from This product was recommended by our heating/air service company and, as previously stated, I am much pleased with this smoke alarm. Over the years we have had a number of smoke alarms in our residence and the voice alarm is much preferable to the irritating beep-beep. When you have various smoke alarms on various floors of a house, it becomes a puzzle to distinguish which alarm is beeping and for what purpose. Your product is easily distinguishable as to location in the home and gives the information you need to correct the problem. A big improvement!

Rated 5 out of 5 by from Saved my house I had installed this product the day before and can honestly say it saved me from serious smoke damage in my house I had a wood burning fireplace that I had just loaded up and I went around the corner to the kitchen outside to get some more wood and I heard the Audible Voice talkin and came around the corner to see my living room Belton smoke and the alarm going off I had hit and closed the fireplace flue with the last login thrown in but because the warning went off so fast I was able to get in there get it back open and then by opening doors and a fan on I had no smoke damage in my house but it was because of how well my alarm worked
