Our community has rated this post as helpful. If you agree, why not thank ShadowP

Reviews complain about dim screen, bad battery life and bad usb cable (can't have it on a stand and charging with included cable).

This is actually $30 and came out to $20 with a promotional credit. Not bad, worth a try for sure!

Why would anyone care about CO2 level in their house?

Because carbon dioxide is odorless and can kill at higher levels.

It looks like a good CO2 monitor, but not an air quality monitor. It uses NDIR so it's accurate for co2, but no VOC sensing or PM (dust/smoke) sensing at all.
