The adapter was purchased for use in Singapore (type G, BS 1363). Half a year, I have used it every day and it still holds, the workmanship is very good. This adapter is designed for the round plug (eg notebook power adapter) needed with outer conductor, ie type F (Schuko). Unfortunately, many adapters support only the flat Euro plug (Type C). For some countries, in addition you need a transformer (USA: 110V), which is not included in this plug course.
