This item has an easy installation, digital reader.great product.

Bought to use for camping in tent, but better off using in a solid structure

I thought this was a combo Smoke/CO detector. It is a nice quality but am returning it since I need the combo detector

I bought this to replace one in my motorhome which started beeping the code for "end of life", which I believe was 6 years. Note that on the underside of the unit was a 'cheat sheet' of how many beeps meant what; i.e. low battery, end of life, etc.I'd wanted to get one that was the same size and hopefully even be able to use the same mounting plate to save having to add more holes in the ceiling. I was a bit taken aback that this unit is so entirely "generic" with no possible way to know who made it or sold it. I'm not getting a warm, fuzzy feeling. I kind of like it when manufacturers, Chinese or not, are proud enough of their product to put their name on it.Also, another reviewer mentioned that he tested his CO alarm by exhaling CO2 into a bag. (We all learned in school that we breath in air and breath out CO2.) Well, CO and CO2 are completely different and a CO meter (this one) won't read CO2. CO2 is a product of combustion which means it comes out of the tailpipe of an internal combustion engine (gas or diesel engine).I think I'm going to go back to the drawing board and see if there isn't a different one that at least has a name on it.

Today is Jan 14,2024. I purchased this Aug. 23, 2023. On Jan 13th the alarm went off, not the low battery warning but the carbon monoxide warning went off. I took it and me to fresh air. It would not go off even pressing the reset button. I had to take the batteries out. I have another brand carbon monoxide that I put in the room that this one was going off in and it did not show any reading of any sort. So now a day later the batteries have been out for over 24 hours and when I put them back they go off. So either I have a defective one or the whole entire brand is not good. My life could depend upon this device, so I am not feeling good about it at all. The company should give me a full refund upon reading this, but I doubt that will happen.

This device doesn't seem to function as I would expect the digital display reads 000ppm of CO2, which should be wrong under any circumstance, but I even put it in a clear bag, and rebreathed the air in and out of the bag until it wasn't giving me any oxygen, then while keeping the bag closed I caught my breath with normal air, exhaled as much as possible, and proceeded to rebreath the already useless air inside of the bag for as long as I could go without real air. I managed to have the bag with the device inside be occupied by nothing but air that couldn't be breathed anymore. As we know that happens because of too much CO2 inside, not because of a lack of oxygen, and yet the display still read 000 parts per million, and the siren never chirped, one would figure that by filling the bag with air so full of CO2 that it no longer supported life, that it would read at least a little bit of CO2 in there. ANYONE that understands how breathing works will agree that this experiment indicates that the device doesn't work. The test button on the device worked fine and the display lit up and provided a reading of 000ppm do logically the failure was in the devices ability to recognize CO2 in its environment, which is it's only function... Someone trusting this to work could seriously die thinking they were properly equipped. If enough of these sell it will certainly cost someone their life eventually.
