Review on 🌬️ Enhance Indoor Air Quality with an Indoor Carbon Dioxide Meter by Jason Melvin

One month after receiving the device: The display is easy to read even in bright daylight and from a wide viewing angle. CO2 readings are more accurate than I expected (see image). My calibrated meter reads 397ppm versus 403ppm for the monitor which is only a 2% difference. It's great for the price. Temperature and humidity levels are also good. The values in the images are off because I didn't wait long enough for them to align after moving the devices from indoors to outdoors. The only annoying thing is that the manual is out of date and one setting is not configured as described (sorry I forgot which setting at the time of writing this article).
