    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

    The device makes an alarm when I push the test button. As far as I know it will probably detect the hazards that it is designed for.

    Family Safety Is My Prime Concern
    1/9/2016

    Customer review by Firefighter88

    5.0 stars 1/9/2016 by Firefighter88
    by Firefighter88

    This is a fine product to protect your family from colorless and odorless carbon monoxide gas. Carbon monoxide gas is more rapidly absorbed into the bloodstream than oxygen. Left undetected, unspeakable health consequences can ensue. This alarm also detects the presence of explosive gases, natural and lp. Now we know that we can smell them when awake, but what about when we are sleeping? I for one don't want to take a chance and risk an explosion while we are sleeping. I want to wake to the warning alarm and take action! This alarm has a nice form factor, smaller than the Kidde Night Hawk which I have previously owned. The display remains dark unless alarm or testing conditions exist, whereas the Night Hawk continuously maintains a display even when operating on battery back up. The LED display just eats up battery power when no alarm condition exists. On more than one occasion the low battery alarm has sounded after an extended power failure. I find this a bother given the battery power appears to be diminished sooner than it should. This alarm also features an end of life notification on the display which makes it easy to know when the unit needs to be replaced. The Night Hawk also has this feature, but it displays Error whereas this unit displays End. End is much more meaningful to me. The last nice feature is the battery guage built into the display. It is easy to guage if the battery needs replacing.

    Thought the battery back up would last longer. Wish I had been told it was not meant for primary use. Other than that it works fine.

    Can not read the display, very dimly lit. Poor design. Returned it and puchased a Kidde brand Gas detector, much better product, can clearly see the display read out.

    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....so it's hard to tell if it works. However.....it has not gone off for a false alarm and has not been annoying. Hopefully if we need it to save our lives....it will.

    Gas Heating with Family Safety

    4.0 stars 1/5/2015 by GPRogers
    by GPRogers

    Having a detector monitoring the spaces heated by gas stoves, fireplaces, etc., is a smart provision for all homeowners. This unit monitors CO (Carbon Monoxide) AND Explosive gas (aka: LP, Propane, Bottled, etc) or Natural gas (aka City Gas, etc)). One shortcoming: there are no test gas samples to confirm the detection readiness. Wouldn't it be great if the fuel suppliers could test these devices with known concentrations of these gasses!!
