I have had this unit for about a month. I have moved the unit within my house often and leave in the room for at least a week. I saw the reading from each room. I have made a few changes to air circulation in some rooms.
The worse room is our kitchen, but with cooking (vegetarian) there are still problems according to this unit. There is little I can do about the air quality in this room during those times. I have fans in the room as well as doors which are kept open. After a while, it gives me good readings.
I like the unit, and I am happy I purchase it on Indiegogo.
Bottom Line: Yes, I would recommend this to a friend
