The male carries the CE mark and is very solidly built. The contacts appear solid to me. In the Schukoadapter I can push each flat plug and safety plug and pull it out again without difficulty. As is common in the UK, the connector is also provided with a 13 amp fuse.
I see no reason not currently recommended this Reisestecker without restrictions. Unfortunately there are still reviews published that probably concern another / older (previous) model. This has initially quite confused me.
