  • 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.!

  • Never makes a sound yet works perfect....

    What a brilliant idea. Makes me feel so much more comfortable while away from home, knowing the my app will alert me. Thats just the beginning, watch the video on nest website to truly understand all this little guy Then come back to hsn to purchase of course. The price is a bargain for the piece of mind.

  • Finally Nest On HSN

    Shipping was very quick. These were very easy to install and went over existing holes from previous smoke alarms. I'm not electrician but was able to determine which switch to turn off. May consider two more battery model to place in two areas for extra security
