Awesome duo at a great price
these are incredibly nice items. they are constructed well. they are easy to use and very easy to put up rather than using the screws. I opted to use double stick tape which actually worked out a lot better. tested them. made sure that they were working perfect. everything was fine. The smoke alarm comes with a 10-year guarantee pre-installed battery. you don't have to do anything about the battery for 10 years guarantee. according to the box, the CO2 detector takes two AA batteries uses a little bit more juice so you will have to replace the batteries occasionally. but there is a light on it that will tell you when you need to replace the batteries. very easy to put the batteries in and out. If I could have given them 10 stars I would have
It was time to replace the CO2 monitor I had. Old age. I jumped on this offer for a CO monitor offered. I have both in my master bedroom and I am confident that I will be audibly notified should a problem arises.
The fire alarm appears to work well, but the carbon monoxide monitor does seem to work. I will have to try to figure it out more. Perhaps the batteries provided do not work. My previous Kidde fire alarm worked really well, hopefully this one will too.
Less than a week and it doesn't work. Was a random thought to even press the test button as I walked by and nothing. Beeped when I rotated it on the holder day 1 and dead by day 6. Glad I tested instead of trusting my family's safety to this thing.
i ordered a 3 pack. item incorrect
The carbon dioxide alarm was defective. The carbon monoxide had no issues. It was very frustrating to have it defective out the box. We followed all the instructions and it was clearly defective, since it’s a built in battery.
Same as some of the other reviewers. CO detector worked - at least the test fature worked. Smoke detector wouldn't even test so doubt it would work. Used to trust the Kidde name. Now not sure - at least at this "value" price point
the carbon manoxide work, the smoke detector is defective, but because i buy a package of both, I could not return the smoke detector alone
Bought this today so I have more than just one smoke alarm and carbon monoxide detector. I got home and took both alarms out of the package and put the batteries in the carbon monoxide alarm. Alarm immediately does a loud chirp and then stops chirping. Green light flashes rapidly (every second). Can’t get it to “test”. Then the red light lights up and stays lit up but no chirping or alarm to go with it. Owners manual says that batteries are low or bad unit. Replaced the batteries and is still doing the same thing which means the alarm is bad and malfunctioning. On top of ALL that, the smoke alarm doesn’t even work… these are both fresh out of the package! I will be returning tomorrow. So frustrating and not looking forward to the hassle of going back to Walmart !!
