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

I bought 2 of these, 1 for home and 1 for my business. The one in the house would turn itself off at random times after a day of use, prompting us to leave the house immediately and call the gas company. It scared us to death at first, but as I watched the PPM display, it immediately counted down to zero and stayed there. Windows could not be opened, ventilation was not introduced. Then I changed it to the one in the store and the same thing happened. Out of curiosity, I started the car at my supermarket and let it run for 15 minutes with the doors closed (I was outside) and the meter only showed 80ppm and the alarm didn't go off. These things are pure junk and will kill someone. Don't buy this. EDIT: This company contacted me on 05/26/2020 and offered Revain a $25 gift card if I delete my review. NO WAY! Money is no object when it comes to protecting people from harm from an inferior product like this.
