+1, I'd like to buy one, but it's difficult to tell what works well. Currently thinking about this one: https://shop.aranet.com/europe/product/aranet4-home https://shop.aranet.com/europe/product/aranet4-home but don't have a reference how good it is. I just assume it's better than the CO2Meter RAD-0301, which costs 3x less, but it could be I'm just paying for the battery. Anyone has good recommendations?
