    • Reliable!
Color: Orange
I checked it out by approaching our car as it was running. When I got to the back of the car the tester went crazy. It left NO doubt that it sensed the gas in the air. For a while, it was giving low readings from the traces on my clothing! Great peace of mind for not a lot of money. VERY PLEASED!

    • Works very well
Color: Orange
As one guy did in a video, I tried it next to my car exhaust. Wow, the reading went really high immediately. This gave me the confidence that it could at least detect CO. I then tried it at all my heating vents in the house while the heat was on. Zero everywhere.

    • Happy with it but for the battery cover !
I tested this device against my wife's exhaust with the engine running and the garage door open. As soon as I got close to the exhaust, the detector was angry red with alarm bleeping nonstop, kudos ! As I walked away slowly from the exhaust, the scale gradually went down the on the monitor, then it turned green as soon as I walked into the living area and the connecting garage door was shut. So that gave me peace of mind that it works. I intend to use it to verify my combo ceiling mounted CO/Fire detector which recently has intermittently been going off when the furnace turns ON, even with new batteries. Now, I shall have the peace of mind knowing that it is not CO ticking off the alarm. In addition to the ceiling mounted CO/Fire detector, I also have a plug in CO detector. Cannot be over cautious with CO. I took away 1 star because the battery cover is the screw in type. This I find annoyingly inconveniencing in any appliance. It means use of another hardware, a screwdriver to remove the cover to change the batteries. This is one of several appliances ,I do not intend to leave the battery inside indefinitely, since hopefully it will be seldom used. So I think it is an inconvenience to always have to look for a 2.5 star screw driver any time I need to use the device just to put in the batteries. Why they could not design it with a slip on battery cover, which should be cheaper to make beats my imagination. Hope, they make future ones with a slip on battery cover. ... show more

I have been looking at much more complex units to provide detection of multiple gasses order this one because of a immediate need, great price, quick delivery, easy to read display with PPM , seems to be built well and should last.

    • It may be good enough depending on application
Color: Orange
In my test it definitely works when exposed to the higher levels of carbon monoxide but I question its effectiveness at reading the lower levels of carbon monoxide, overall it does work

    • Can Save Lives!
Color: Orange
Bought a new home and the CO detector was going off intermittently. Saw this hand held detector on a YouTube video and purchased it. Arrived the next day. After detective work, dscovered the hot water heater vent pipe covered over by new insulation in the crawl space had been cut off and was not vented to the outside! The reason for the intermittent alarms was the hw heater was a tankless heater so was only venting when dishwasher was going, showers taken, etc. The Firemen, who arrived with their own detectors were impressed we had the foresight to purchase this! ... show more
