Great replacement alarm.

Worked for 4 months and then started beeping intermittently. New batteries did not help. Placed outside still beeped. It cost me almost $20 to return for warranty replacement. NOT HAPPY!

I love these smoke and carbon monoxide detectors. Screw up the bracket, write the date installed on the sticker, turn to activate and forget it for ten years. When it’s time to replace, just repeat the process and your allset for another ten years.

Because it was not the one I originally wanted/picked out but the substitute cost more than the original one that I picked out. I didn’t have enough time to respond so I just excepted the item.

It started going off randomly in the middle of the night after only a month after installing it. The only way to stop it is to permanently disable it when you turn it to off.

I love that it's a smoke AND carbon monoxide detector in one. The installation was easy.... I am so happy to have peace of mind that my family is being protected.
