This particular one, as it states, does not have a cable. This does not mean that it will fit into wireless or telepathic sockets, but rather that an electrician is needed to install a cable and a suitable plug for the application. Do not purchase it if you do not want to hire an electrician or do not have electrical skills.

Its contacts are quite good and its plastics are reasonably durable. For a total load of up to a standard socket (16A), it's fine. I wouldn't attempt alchemy to place larger loads on it, as its conductive parts are not sufficiently large.
