When I listened to my colleagues, the adapter in their house broke down yesterday, but her husband was not at home. She didn’t know much about it herself, so she didn’t think about it. Today, when her husband came back from a business trip to see where the adapter was, the question was whether to replace it or to repair it. She said to me all morning that she still had to know a little bit of this knowledge, otherwise everything in daily life can not be separated from her husband, I said that in fact, I do not know adapter, anyway, it is not often a problem regardless of whether you understand it should not have much impact. But the general quality of adapters is very good, not easy to appear some problems in our family have been used for many years and have not appeared any problems.
