We live in an area where the air quality is frequently significantly impacted by wildfires within a few hundred miles, and everyone in the household has asthma and allergies to some degree. Usually, these sorts of devices are in the several hundred dollars price range, and sync with an app and are part of a community and all this stuff. This one doesn't have those extra features of app connectivity, but it tells all the same information for a fraction of the price. It's easy to read for anyone, and has intuitive information presentation for those who don't know specific HCHO, TVOC, Pm2.5/10 etc. with the 'AQI good-poor' scale, which is also color coded. We're also a household who really likes to leave doors and windows open for air circulation, but keep a close eye on the air quality to know when to close up. Frequently, the two nearest air stations to us have conflicting information, so this makes it really handy to see what the info is for exactly where we are. Charges easily with standard usb-c cable, and super easy to set up and just use. Haven't even tried to change the clock because theres clocks everywhere, so we just use it for its other functions. Quite like, and now the family checks here to inform our indoor/outdoor activities.
