The transmission rate is very good both at 1 m cable, as well as the 2 m cable.
The phone also charges with 2 m cable almost as quickly as with the 1 m cable -'ve done here at cheaper 2m cables already very bad experience.
For processing:
The cable itself is well made. The gold connectors are very good.
BUT:
The chrome-colored plastic in the injection molding plugs do not like it - looks like committee-Ware.
I have ordered 2x a 2 m cable and 1x a 1m cable and all were delivered with exfoliated chromium at the edges or at the transition to the gray plastic back.
In a cable the chrome-colored plastic has a crack itself and in another is a deep scratch in the chrome.
In my 3 cables none of the 6 connector is impeccable!
Too bad that was not working here clean. Otherwise the cables are in fact recommended genuine.
