Piece of mind device
Would Not RecommendI like that this product does not have replaceable batteries thus eliminating any maintenance of this unit. This SD/CO unit has a 10 year life span as does its batterie(s). After 10 years, it must be replaced to maintain service coverage which is normal for these types of devices.

Way too sensitive.
Too sensitive. Every time I use my stove top it goes off, and it's not even that close to it.

A $60 mistake waiting to happen
Would Not RecommendThere is a plastic tab that needs to be removed to use this device, but it sits right on top of a switch. Naturally, you’d assume this is the "on" switch—it’s not. Flipping it immediately bricks the device, and there’s no way to reset it. While there is a tiny warning on the unit itself, there is nothing in the printed manual about the tag to be removed. $60 down the drain due to a massive design flaw.
Hi Mouner, we are sorry to hear about this. We will be happy to take a look at this and replace your unit under warranty. At your convenience please ...

Great fix and forget smoke/monoxide detector
Would RecommendVery easy to install, just be sure you have the right hard wire connections complete in the ceiling. If you do, it’s a simple plug and play.

Quick and easy replacement
Would RecommendWe bought this because our old smoke/CO detector reached the end of its 10 year lifespan. Replacement was quick and easy. I really liked that it still uses the same wiring harness as the old one so I didn't have to do any rewiring.

Hi Chop, thank you for bringing this to our attention. To reduce nuisance alarms from cooking, keep it at least 10 feet away from cooking appliances ...
