Optical Top - with me unfortunately a flop.

Packed the cable was in a blister pack. The cable is very high quality and smell thankfully not, as is common with many other cables.
I had provided the cable for charging and data exchange on a laptop, but here I was sadly disappointed.

My first experience:
I have not tried the cable on the day of arrival, I am thanks to the optically very good impression of the work assumed the cable perfectly. Far from it ... Overnight I have hung on a Brand Power Bank to charge it to my smartphone. The next morning, the disappointment, 3%! The cable invites sometimes, sometimes not ... It's not the position as you plug in the connector, because sitting very firm and solid in the device.
I tried to exchange data via a desktop software on a Mac and a Wind.7. Probably a bad contact etc.
Unfortunately I was very disappointed because really makes the cable a top impression. (That's why 3 stars)

Probably I had after all unlucky, I was unfortunately so upset because I really rely on in the week that I have the cable sent back.
(Of almost 150 BESTELLUNGNE THE FIRST RETURN)
Return worked fine via Amazon.
