The socket is sold without the metal plates inside, but it cannot be used in this way. The description does not describe that the plates are sold separately, nor does the seller inform me that only the plastic socket is sold without the metal plates inside. This means that in order to use the product I have to order the plates, pay for delivery and wait 30-40 days to be able to use the socket! I bought many different connectors, but never without plates! it's like giving a person a pen without ink and telling him - write!
