I would give this device 5 stars... it appears to work very well, but there are bugs in the software.... "Good" air quality is only from when the reading is greater than 0, so when the reading is zero, (no particles at all), the display goes red, and it shows "Severely Pollated" (SIC). Polluted is spelled incorrectly. A minor detail, but should be addressed, see image.

kalynn3 I don't have this device, but red zero may be a warning that the sensor is not working, or it assumes that because it's reading nothing.
