Looked great. But the only thing that it does is show the room temperature and humidity. IT DOES NOT. REPEAT DOES NOT READ CO2 LEVEL. Do not buy. I wish I read the 1star reviews, would have saved money and cought this sooner.

A nice alarm clock to place at the entrance

It looks good but has unreliable readings, and the battery no longer lasts. This isn’t a monitor you can trust—or even use comfortably. After my apartment's interior renovations, there was so much dust that we were coughing. However, it still appears in good condition throughout my entire place, so there’s no way to determine if anything is calibrated correctly.

flimsy construction, unreliable readings, and a battery that feels like an afterthought. This isn’t a monitor you can trust—or even use comfortably. Save yourself the headache.

NOT EASY TO USE. I tried comparing the results with another trusted monitor, and this thing constantly showed wildly different numbers. The VOC and CO2 numbers don’t seem to mean much, and there’s no way to tell if anything is actually calibrated correctly.
