[This review was collected as part of a promotion.] Zero complaints with this smoke detector. This had everything we needed to get it installed. And the instructions were easy to follow. A great replacement

Like others have complained, there must be a faulty batch of batteries with this model. It is beeping randomly with the battery error it goes away when you hit the test button, but not until you wake the entire house in the middle of the night.

It's only been 8 months and we have had 2 units fail. They just go off indefinitely even though there is no fire or CO. TWO of them failed, not even 10% of the claimed amount of use time. Really feels like a scam.

I just purchased this home 2 years ago and I think I have a defective smoke and carbon monoxide alarm, why, it’s to soon for this to give me a problem.

[This review was collected as part of a promotion.] We put this in our littlest room for peace of mind since it is a combo. We have no had any complaints. The battery has been fine and it was very easy to install.

I put in 8 smoke units and 3 combo smoke and CO. Two of them failed in three months. I am worried about the others now. They always fail after 12:00 PM. Must be built into the program.

[This review was collected as part of a promotion.] Received this combo smoke and carbon monoxide alarm. Very nice item. We very easy to install. My other alarm was old and needing replacement. Very excited to get this new one.

bought about 2 months ago....Could not get alarm to stop...had to disconnect battery to get it stopped...thus any warranty is not honored. WOULD NOT recommend this product. Wasted money.

[This review was collected as part of a promotion.] Highly recommended it was easy to install and it works well I need like 5 more then I'll feel safe! Haven't had any issues with battery life but it's only been a month

[This review was collected as part of a promotion.] Well my husband was excited about this one he says you can never have enough it works as far as we know with no issues! We like that it doesn’t only detect smoke but carbon monoxide too
