Basic - no more, no less

At first I was surprised by the relatively high number of negative reviews, but it is of course understandable if the plug, even after adjusting experiments with the rotary ring, does not fit. You can freely overlooked very easily that you can vary its circumference with said rotating ring and really easy which is then not exactly.

However, my experience ranges from more positive to none at criticism because the device into my cigarette lighter from the beginning "bombproof" is stuck (after I had adjusted it with the bezel). The catch to adjust the angle of the connector, works fine and is helpful. In endurance test with two devices (Navi and mobile) is no weaknesses revealed both were adequately supplied and steady power.

Conclusion
Overall, this distribution for me generally fulfilled its job without complaint and remains within its Product Information / vow. It is not unusual, but just basic, as the name suggests. And in conjunction with the low price, because if it fits into your cigarette lighter, a good investment. My tip easily test and if it does not fit despite adjustment, easy return. So far, Amazon has indeed shown here very accommodating.
