Otherwise, it's very convenient not to have to constantly raise the cover. Even with a correspondingly good power adapter recharges the phone quite quickly (not a big difference to the normal cable).
In this respect, my recommendation, even if it is as I said a little hakelig ... 4/5.
Update after six weeks: unfortunately I have my vote revise - after six weeks already wobbles, the cable does not load more reliable - a pity. Seems to be a processing problem.
