These are affordable, discreet, and gives me peace of mind that I am protecting my family. The alert is really loud if texted, and I like that there is battery backup in case we lose power. I purchased off of Amazon for about $20, and it should last for a very long time.

I got a 3pk of these Alarms from Smiley360 & couldn't be happier. They've definitely helped me sleep better at night, knowing my family is safe. They each come with their own 9V battery (included), easy to read instructions & a wall mount (optional). They're super simple to install. I set up one on each floor of my house and didn't need the hubby's help at all, GO ME! There's a test button right on the front. The alarm is very loud, which ensures that you'll hear it, no matter what room of the house you're in! I HIGHLY RECOMMEND that every homeowner/parent has at least one in their home, especially if you have kids in the household.
*** Carbon Monoxide is known as the silent killer- you cant see it, you cant smell it & you cant taste it either! Carbon Monoxide Poisoning is the LEADING CAUSE of ACCIDENTAL DEATHS in THE UNITED STATES ! So PLEASE, Go pick yourself up a First Alert Carbon Monoxide Alarm ; you WON'T be sorry!

I got mine at Lowe's on sale and have on 3 of my homes levels. My only con is that I prefer have alarms that can be plugged in and have battery back up. I also prefer natural gas/carbon monoxide alarms.

When I moved I wanted one of these because I was living alone and you never know when something can happen. This is a very trusted brand and I stand behind it! I like that it is had sensors too with the volume that can go up so you can hear it through out the house

The only reason I didn't give this a higher rating is because I have this exact product inside the landing of my basement staircase and it didn't detect the carbon monoxide that apparently had been leaking into my basement! I have a large, old home and I know that my basement is VERY drafty but our boiler (that was leaking) isn't far from our basement stair well... I feel that the product should've worked to alert us. Luckily I had the gas shut off because it was warm and the gas wasn't needed. Regardless,this detector didn't alert us.

Living in an at home daycare, we have these all over my house. They are pretty small and do not take up much room, however, they are their to save my life & I love them for that! I've never had an issue with Carbon monoxide in my house, but I know if I did, this device would save my family & my life as well as the little ones when they are here! Everyone needs one of these in their home.

We have three of these in our home. One in our dining room, one in the master bedroom and one in the basement. When we test them, they are very loud which is reassuring. It helps give us a peace of mind for our home and family.

Beeps loud but takes ore than 4 minuets to detected carbon monoxide due to the sensor not always being on and it has to be more the 400 parts before it will even alarm

Works as far as I know? I'm not sure if it's effective or not as far as the Co2 detection, since it's never gone off. However, the few times it's beeped it's been SUPER loud, (ie when battery is dying). So far ok.

Cute design. I like that it runs on AA batteries, which I always have, verses 9volt batteries that I don't. Appears to be functioning correctly, but luckily I've never had it go off. (No CO problems!)
