Extremely pleased with these devices. I have had them about a month, testing them against other devices. Their function has been as good if not superior to much more expensive CO2 detectors I have. As they are so inexpensive, have started to give them to family members so they can be more aware of their CO and CO2 levels in their home or campers. Test them for yourself as I did by putting them with dry ice or drain cleaner (off gas) - They work!

So far it seems to work just fine. Bright and clear display. Whe.n you first turn it on, let it sit a while to get steady readings. Could only verify CO2 at this time by breathing on it and the numbers went way up.

This is an absolute wonderful device, and outperforms other models which are double or triple in price.
Gives me peace of mind to know the quality of air around me.
I also find it funny when the alarm goes crazy when I open bottles of alcohol around it haha
