    It worked for me

    Customer review by JDmom247

    I use this model downstairs. One night another (brand) of carbon monoxide detector went off upstairs in one of the back bedrooms. To be sure it wasnt a false alarm I took this model and rushed upstairs. It took an immediate reading and started sounding off before I could blink. I have had it for about 4 months and not once had a false alarm. When the fire department came they had the same PPM reading as this device. Pretty good product IMO. I have 3 kids and I trust it. Its just a lil on the pricey side (but worth it).I paid about $53 in store

    I bought this product a couple of weeks ago. We had installed a propane gas log set in the fireplace and I wanted it to detect a possible gas leak if that's ever the case. We do not leave the logs burning while sleeping, so the carbon monoxide detector is just a bonus. It was easy to plug in and mount on the faceplate of the plug. The little screen is easy to read. It has not gone off unless I was testing it's hard to tell if it works. has not gone off for a false alarm and has not been annoying. Hopefully if we need it to save our will.
