IQAir AirVisual Pro Air Quality Monitor Indoor/Outdoor

Brand New unopened box: IQAir AirVisual Pro indoor + outdoor air quality monitor in white. Features a digital display for real-time data. Purchased a few months ago, never opened or used. This is the highest rated in its category and the least expensive, including both indoor and outdoor. IQAir has the best weather service, including an app based system. This is completely unopened: I just missed the return window. Ridiculous offers will be ignored.
