Here is a detailed assessment of the delivery up to the test.

I have ordered the goods on Saturday. The delivery went gelativ fast, so today on Thursday it has come within 5 days.
The charging cable was contained in a small foam-padded letter, which protects it from severe shocks.
As I unpacked it, it was freezing. so I had to let them sit on the heating it for now.
And then I did it once tested on my completely empty 3DS XL.
I have the cable connected directly to the 3DS XL, and plugged the USB connector to an adapter, and a power battery.
On all 2 things it loads without problems, there is no loose contact. On 3DS XL and the USB adapter it holds as well as the original charging cable, so you need have no fear that it is too easy rausziehbar.
However, I have discovered a downside: The USB charger cable is not with the charging station kompantibel. ie It can indeed poke without problems, but the orange charge LED from 3DS XL at irregular intervals flashes continuously rum.
So far I have still found no further problems. Nevertheless, if at some point should be any difficulties in quality (for example, internal cable breakage, loose contact, etc.) I'm going to submit a new review with the appropriate rating.
