Starting with the already mentioned blue light that half the room lights, continue over the poor fit of the phone in the station. It tends to slip up, that is away from the contacts and without you notice it is the morning of the battery all because has not been charged. Finally, one has to regular use, press the Iphone with force to the contacts so that contact is maintained and has really long there either.
So it gets to me a point, because I have to give at least one.
