Multi-Function Car Carbon Monoxide Detector, Fast Car Charger, USB C Quick Charge 3.0 Adapter for Mobile Phone,Tablet,Camera,Navigator, CO Alarm Detector with Emergency Glass Breaker(Gold)

I guess it was an impulse buy - not really sure how useful the monoxide sensor is - basically how do I know it even works ( unless I hear the alarm or something ).Main regret being the higher price of it - compared to other normal car chargers . Is it worth the extra $ for something which I am unsure if it even works properly.( Have not taken the time to test the monoxide functionality in some other way as other folks may have done)

Works ok but its weight makes it fall out of the socket sometimes.
