Good quality, efficient and polarized

I agree with the first review. The cable is solid, the magnet is not polarized and therefore begins in one direction (writing Record the same side as the front of the phone). This detail is VERY IMPORTANT because when reversing, you might destroy your phone (it does not turn over and charge).

The magnetic force is ideal in the sense that it does not endomagera port (common problem on other cable magnet too powerful). But because of this, avoid touching the outlet.
The LED is certe convenient but too strong and therefore embarrassing night.
The build quality is excellent, the cable is thick, and connectors are metal.

One negative anyway but do not depend on the cable: When the branch (on Sony Xperia Z Ultra in my case) He can "react" on some mobile applications:
- It generates an update of the pages on the net.
- Made "freezer" Mobile Magic 2015
- Resets playing a YouTube video in early

Maos this may be related to the Xperia Z Ultra, not the cable. Note that these phenomena do not occur when I plug in a micro USB cable.
