  • I feel so safe!

    Love the confidence it gives when we have to travel. Love the app that goes with it. Love the fact that it tests itself on a monthly basis. Love the motion activated night light. It;s great!!

  • Super Awesome and easy set up.

    This Nest Protect Battery-Powered Smart Smoke/CO2 Alarm/Detector is super amazing! I was impressed with the easy set up and installation. I've replaced my (upstairs hallway) standard smoke detector with this one and I plan to replace my downstairs standard smoke detector with this one as well. I am just praying for a sale :). It also has the coolest night light, it detects your present and provides a soft illumination... that you can adjust with your app. I also, hope to purchase the NEST smart thermostat in the near future as well. Thanks HSN for bringing us innovative quality products.

  • Awesome Detectors!!!

    This product is great! Expensive but worth the money. I should have purchased the three pack at Sam's had I known how great these babies were. I highly recommend this smart detector. The alarm is very loud and your neighbors can hear it but if that means saving a life then that's great.

  • Lots of features

    The Nest protect is much more than a smoke and carbon dioxide detector. It is extremely smart. Pair this with your phone and no matter where you are you will know if the alarm goes off at home. By the way, the app will also give you a brief weather forecast. Installation and pairing with my phone was easy. It took about 10 min. For the whole process. There is also a "night light" feature which is motion activated. I love this and highly recommend.!
