Fabulous device to monitor the important parameters to determine quality of air we breathe. The digital device came fully charged and once turned ON, was fully functional with quite stable readings in about 10 minutes. It's a wonderful design, smaller than what I imagined. The unit is value for money and probably be a regular feature in every home due to the environmental changes we are all encountering worldwide.
