Review on 🔥 2-in-1 Natural Gas and Carbon Monoxide Detector: Reliable Plug-in Co Detector for Kitchen/Home, UL2034 Certified by Brian Summers

I tested this detector two ways - placing it directly in front of the propane tank nozzle when I disconnected the hose - I definitely smelled propane - but this detector did NO squeaks - Nothing. (photo) 2nd test I took a small propane tank and slowly opened it - it took quite a long time and quite a bit of gas before the device finally sounded the alarm. (see video) In my opinion there must have been too much gas in the area prior to the alarm - until the alarm finally sounded a person could detect a gas leak simply by smell - this unit should be MORE SENSITIVE and alarm for LESS gas (e.g . slow leak) - I return it.
