Customers say
Customers find the air quality monitor easy to set up and use, with a vivid display that’s easy to read, and appreciate its functionality and CO2 level monitoring capabilities. However, the accuracy and quality receive mixed reviews, with some finding it reliable while others report inaccurate readings and poor construction. The WiFi connectivity and battery life are also mixed aspects – while the WiFi feature is nice, many report connection issues, and the rechargeable battery only lasts about a day.
