Use it in my electric car, the heater isnt that good and have alot of moisture in it. first of all shipment was fast to NL, within 2 weeks. In the car without the dehumidifier i get about 90% RH inside anr fogged up windows all the time. i now used to dehumidifier for about 1 week and it turned green! Humidity drops by about 15% so to 75-80% very good. Fogging up happens way less. quite happy with it. I ordered a second one so that i have 2 in my car. it works for sure! fits my my door cupholder.
