As many of you know, currently I am considering the Wonpro Nano as the best plug adapter so I will compare it to that. Advantages: the EU height solution is brilliant. The Wonpro Nano solves it by allowing to screw out the plugs which makes it a bit tricky to plug it in. This one? This one just fits in a grounded Schuko outlet whole. Good trick if I ever saw one. Disadvantages: only one plug instead of two and only US at that. However, they have a ridiculously small USB charger/power strip with as many as four universal plugs and two USB as well

This definitely gets the coveted "recommended by chx" award

I ordered a Mogics Bagel inc. the adapter.
Also, this seems to come from the same company who created the
