The cable is high-quality and works in Heimbebrauch as intended. When Z Ultra is the most stable when the phone is flat. But that is due to the very narrow design of the Ultra. Had it hoped to be able to use in the car. This would require the magnet but its still much stronger. But that is for other magnetic cables the same way. Why do I still give 5 *? For me, a wonderful long Micro USB cable was additionally in charge. This helps me by the length prima in the car. Therefore, 5 * instead of only 4. The dealer gets another extra praise when assessing the delivery.
