  • Fire Fire!

    I saw this unit and it makes better sense to have this than the others that are out there. It is connected to my wifi and will alert me on my phone if I am not home. The night light is just bright enough to light a path in the hall and not bright enough to wake you up.

  • Attractive Alarm

    Got a coupon code from HSN, so decided to buy this, had my eye on one for while but didn't want to spend $119. The product is smaller than I thought, which is good thing. Also, lights up at night which is cool feature. Works well with the Nest app.
