In GREAT condition! Does not come with any scent cartridge. Play any scent in any room at any time. All from your phone! (you don’t need to use this option, you can just turn it off and on as well.) Aera can connect over WiFi if you want. It will scent large and small spaces and can have up to 20 scent schedules each. Smell a different fragrance or essential oil scent in each room.
