three pole input, bipolar output

I am disappointed and a bit cheated by this product. The UK side has, as shown, three poles (phase, neutral conductor and earth leakage current) - the adapter side (for most of us here probably Austria and Germany) has only * two * poles (earth leakage current is missing) ,
Three-pole safety plug go purely natural, but the brackets take into space.

Of course, the adapter will still work but that one could also read somewhere before that the FI Funktionialitaet lost.
