It looks good. But the reviews on Amazon says it’s not having a good battery life. How’s it for you? I don’t need to travel that much so I can keep it plugged in all the time?
One thing that it lacks is WiFi connectivity - all syncing needs to be done via bluetooth. Which makes sense since it's portable but WiFi would be nice when it's at home. But the device is open and their site gives you ways to make it WiFi compatible if you so desired.
I originally found it through a report that showed it as effective as expensive air quality testing gear. It happened to be the only portable one as well that rated that well.
