As other reviewers have mentioned, I also got this device for constant monitoring, but it does not work for that purpose. The battery only lasts a couple days, and it can't continue to monitor while charging because temp is off by 5 or so degrees whenever the USB is attached and it is charging the built-in battery.The alarm went off and it was rather annoying, so I guess that's good... you'll certainly be notified if there is too much CO2 in the area.

I got it as insteresting gadget, not big expectations. I wanted it to be continuous monitor used at home. Really it is not ready for that function.- The rechargeable battery doesn't last even 2 days.- When battery charges then the temperature gets 7-8 degrees C higher than it really is. This makes humidity wrong as well.- It didn't come with charger, just short USB cable.- When it is continuosly connected to a charger then battery is not used as backup. Battery is used and when gets low then starts charging and temperature/humidity get wrong again.- Appears to work, CO2 increases when you breath on it, exhauling CO2.- It is advertised as 5 in 1. I really don't count temperature and humidity as novel test items to be excited about. So only three components are left beyond simple meters.- Manual is not adequate and it is not so "professional" just basic as per manual.

Excellent product that met all my expectations. This product is an air quality monitor. The overall experience is impeccable. The air quality monitor can easily monitor and provide accurate readings, allowing me to keep track of the air quality around me.
