I trusted the positive reviews but obviously all products sold by vendors is not the same, I ordered two identical adapters and 2 boxes broke from first use (normal use I said), barely plug the adapter back in ... I packed all in tape to hold it after all only the plastic had dropped, but now the weld which detaches and creates a false contact, brief 5 euros (postage included) through the window ... It's not expensive but it is not worth the small fee required ...
