The cables have a braided sheath made of a kind of nylon and are thus more flexible and elastic than the usual, cased with plastic cables. They seem to be even more durable and less prone to breakage. So you can better lead and lay it well. And they are thin.
The funniest part is, however, that these cables are used on both sides, so no matter which way they operate. The plugs are good and fit. I have now tried different devices and both the charging and the data transfer function perfectly. You just have to be aware that there are just 2.0 USB cable Micro USB is precisely coupled with 2.0.
Not suitable are these plugs for iPhone or iPad.
I wonder why that was not invented long and is on the market. This innovation is absolutely great. The price for this set is also attractive. Highly recommended.
