Delivery as always fast, but now in the late afternoon - as Hermes and DHL no longer ??? I did not come to the unit test; because although how to proceed according to instructions: - Battery charged to LED blue, - Neither with Galaxy Advance, S3neo nor Samsung Ativ could guarantee connection though "Power" button was pressed, the voice whispered "Power on" and the LED has flashed. I would like to once again make a replacement device a try. However, there are already three reviews with this same error description! The look is very appealing.
