Easy to use and works well.
Well, we know that this smoke detector is good as it goes off when I burn food. Also, it is nice to have the smoke detector and the carbon monoxide detector in the same unit.

Worked well for me
This smoke detector was easy to install and gives great peace of mind. The setup was quick and the unit feels well-built and reliable. The alarm is loud and clear, which is exactly what you want from a safety device. Overall, a dependable detector from a trusted brand.

Easy to install
Simple to install. Fast way to get compliance and safety. Loud enough. No sure how sensitive it's at detecting fire or smoke but no false alarms so far and I sure hope I don't have to face a real one.

Good value
Like the convenience of changing my own batteries!!! One 9 volt battery. Great value smoke/ carbon detector too; as I suspect this one will last longer. ( I’ve bought three of the ten year battery detectors never needs to be changed; except they die after only a couple years. They are Not worth the higher price either.)

Works well
As expected and reasonably priced.

It is NOT a direct replacement.
I copy and pasted two reviews already posted because both are true. Device may be great but the package did not include connectors. These do not fit the device they are replacing, don't know why the proper connectors are not included. I had the same model already in the house so I assumed the new ones would fit with no problem. I was soooo wrong, when I got them I saw the connectors are different which makes no sense if you are replacing the same model. If they changed the way it connects they should put the new type of connectors in the box or mention that the old version can’t connect to the new one. So if you want to install you need to buy those separately which is ridiculous.
