Amazon provides as always quickly and easily. That was about the only good. The delivery consists of two parts. The one is clipped to the screen, the other to the lower part. So it seems that both should be sealed, but it was only the upper part. Apparently I got a return. The lower part was full Fettdatschen and a hook was already canceled. In addition, it does not fit exactly ran. A millimeter is missing and even if it is only a small millimeter, it's fatal. because no matter how you try to hook somewhere it never fits. I will not send it back, because then it gets probably another and I want to avoid. The upper part fits quite well in itself, so I can at least use the. I recommend not to buy this product. Because for the price you can not expect too high quality, but to send an already used and broken product is just naughty.
