Review on Kidde 21026065 Smoke & Carbon Monoxide Alarm: Voice Warning for Ultimate Safety by Sam Hawj

I have a few of these and I like them. They come with a small (quarter to half dollar) mounting bracket and include the screws and anchors needed for installation. Once installed, the device will automatically trigger and go through a smoke and carbon monoxide alert cycle. The only issue I had was that the last unit I ordered from Revain didn't come with the bracket or screws in the manufacturer's blister pack. You will not be able to activate the smoke alarm without a mounting bracket, so ensure the mounting bracket and hardware are included. I am returning this block for exchange. Fortunately, Revain has a good returns policy! Addendum: The exchange set contained all parts. Installed and working.
