Therefore, yet 5 stars from me: I knew what I was getting myself, and have therefore resorted to the rather usual good Brennenstuhl Quality. For what Brennenstuhl saves on intelligent design, they seem at least to be stuck in the product quality: From * not * my Brennenstuhl outlets there were in the past 5 years even any problems. Even with frequent change the plug sockets sit still very good.
So if you can overlook the suboptimal medium version, is well advised with this adapter.
