My husband's birthday is coming up and he used to talk about wanting a purple air sensor. We live in California and have had more than I'd like to see wildfires and poor air quality in our area. -BUT- in the past year we have had two neighbors who have bought these sensors. One is ~400 meters away, NW of us. Another ~500 meters away, SE. And once my husband said with these two sensors, there is not a lot of value to another one for us.
What do you think? Buy him the gadget?
He also has in the past wanted his car detailed, so that's an alternative gift.
