The basic idea: Not many cables lying around and still can connect everything to the USB Repeater.
I ordered directly two sets, one of which I wanted to keep one and give the other.
Now comes the but:
The connectors are not well made and very shaky stuck in bushes, in which maintain normal cable without problems. The problem occurs mainly with the micro-USB B connector. You put because his phone off, one must always make sure whether there is a connection to charge or not.
The supplied and initially perceived as a very practical self-retracting cable had given up the ghost after about two months: cable break. It was more than 20x up and unrolled.
All in all, the set due to the many adapters and practical pocket nonetheless useful -> 3 stars.
