Very expensive and malfunctioning device
My experience with the Uhoo air quality monitor was extremely disappointing. Upon receiving the device, it did not work at all. After weeks of back-and-forth communication with customer service, they finally replaced it with a new unit. This replacement worked for exactly six months before three sensors began malfunctioning. Despite this, customer support insisted that everything was fine, even though the device consistently displayed incorrect readings (e.g., 0 hPa for air pressure, 0 ppm for CO2). If you're considering an air quality monitor, I strongly recommend avoiding Uhoo.
