essentially cheap Friend

product delivered in the first day of the range of the displayed time, properly packaged nothing to say.
product according to the photo, magnet strong enough to Z3.
load 99% due to the small loss (it's a logical magnetic cable), the LED is appreciable, red charging, blue loaded. it is reliable, no flicker worries
can not go wrong polarity sense there is a pole offset.
I coupled the magnetic and micro usb without problems for the phone, but the load does not seem faster, one must take precedence over the other.

affordable price.

there have had the power outlet for a full set.
