This part is very well made. I've never had a car adapter which has virtually kept in my cigarette lighter, like this. The only downside (hence a point deduction) is the extremely bright LED that indicates the status of the adapter. If you drive at night so (my car has a red backlight of the instruments) is the whole interior illuminated in blue - and the driver is distracted in my opinion unacceptable. Therefore, I glued a piece of electrical tape me to the LED. Does not look very good ... but still I know nothing better to do (Edding was insufficient lichtdcht).
