Great little air quality monitor
Works well and shows CO2, temperature, humidity, TVOC, and HCHO clearly. The screen is bright, readings update fast, and the battery lasts a long time. Easy to use and worth the price.

Handy little air quality checker
This works really well for keeping an eye on indoor air. The screen is clear and easy to read, and the numbers update quickly. I like that it shows CO₂ and overall air quality at a glance, so I know when to crack a window or turn on the fan. It’s small, rechargeable, and easy to move from room to room. For the price, it’s a solid tool to understand what’s going on with the air at home or in the car.

False Alarms
Absolute piece of junk. After a couple of months, it started to beep that CO2 was over the limit. I checked it against a couple of other air quality monitors and none of the other ones were even close to the CO2 level that this unit was reporting. It is like a smoke alarm that keeps beeping even when there is no smoke. Unfortunately it was pass the return window and I’m stuck with something that is absolutely useless that emits annoying beeps spontaneously. Save your money and get something better.

Works but battery dies fast
It works but the battery life is really short. If you want it to continuously monitor the air quality it will die in a few hours.Also it has some false positive rate of the particular particle it’s trying to detect.
