ShackcomCombination Smoke and Carbon Monoxide (CO) Detector Alarm 3 Packs, Protect Your Home from Fire and Gas Leaks, Even When You're Away, Battery Operated

I put batteries in it and the alarm sounds. So I put it next to another one to see if it really detected anything, but no it's the only one that continues to go off. If I could give 0 stars I would.

Based on the incorrect English in the packaging, I was worried it wouldn't work. So I put it in a closed small tubberware box with a piece of incense. And it went off. But I could not get it to stop going off. The directions didn't carry through there. But for the price point, I don't care if I have to remove a battery if I avoid burning my kitchen down. So it works!

I bought four of these to replace all the old ones in my house. They were very easy to install. The only problem I had was that these are so much smaller in diameter than the old ones that I was left with a different color wall showing around the outside. Guess I have some painting to do! : )

I bought these for my garage and my shed. They are very sensitive which is good, but the problem is getting them to stop. I pulled them out of the garage into the open air and it took them several minutes before they finally shut off.

Product is small and easy to install and the price is good. Product is use for home protection.

I like that all I had to do was install the batteries and place it in a spot that I thought was good. A light flashes to let me know that he batteries are still good. I highly recommend this product. Lastly, the alarm is loud!

I bought this CO2/Smoke alarm for my camper trailer . It is small and does not look out of place . I hope I never hear it accept for the test but it is good to know it is there .

This combination smoke and carbon monoxide alarm is just great. It was easy to install, and the vendor sent meinstallation instructions ahead of time also, which was very helpful and excellent customer service.I am very happy with this purchase
