I was looking into buying this product. I live in a tri-level house, where would the best place be to put the 2 of these? I have 3 bedrooms up stairs, living room and kitchen in the middle and family room, laundry room and the furnace on bottom level.

How long do the batteries usually last?
Asked by: DJ
I would not wait for batteries to run down for any type of CO detector or smoke detector. It is best to replace them on a yearly basis, whether or not the alarms still function when you press the test button.

When the number 16 pop up is that good

Asked by: Tone
It depends. Wikipedia chart says 5-15 ppm is normal near properly adjusted gas stoves in homes. Another chart says 35 ppm (0.0035%) causes headache and dizziness within six to eight hours of constant exposure. It's about CO slowly building up and preventing hemoglobin in the blood from transporting oxygen to the body.

Why is the back loose, it doesn't stay on snug after you open it to put in the batteries?

Asked by: DDX
Is possible that the batteries are not seated properly.

I was told by gas utility person to get the kiddie without the readout the other leading brand was no good. I have the kn-copp-lp unit with the readout. The other morning it indicate a reading of 31 I changed the filter reset it and it stayed at 0 all night. The burner was going on and off about every minute and half. I called a heating contractor he came by, and when the co levels were checked his detector went up to 52 and remained there I had kidde nighthawk right next to it, and it was reading 0. A couple of the heat exchange burners were cracked. We purchased this home 3 years ago the furnace was replaced five years ago. The house was inspected when we purchased it $700. Get your furnace checked by a professional annually. I am still looking for a detector. It is your life and family.

Easy to set up, and like that they are able to stand on a table top. Like the digital screen, which makes it very easy to monitor!! Have instructed family members what to do if the alarms go off. Will be purchasing some additional units to install at my mother-in-laws home.

The number readout on the screen gives us more confidence of any CO levels being present. This has been a great investment toward my family’s safety.

Rated 1 out of 5 by from Defective One of the units was missing the metal connectors for the battery, making the unit unable to receiver power. A quick fix with tin foil fixed the issue, especially since i only really needed one unit. Pretty poor quality control.

I waited a couple of days and reinserted the batteries and it worked and cycled as it should. Now there are no problems.
