Have this adapter for some time in use, because I own several devices with UK plugs. These devices can be operated wonderfully through this adapter. The adapter "contributes" easy on - so seems a bit clunky - but that's one part of the technique used (the ground terminal in the plug is not "push through" to, but correctly wired to the "German" plug) on the other hand paid the robustness. All in all a recommendable product with which I have never had problems. For travel in respective countries, the unit provides sure - here then comes to fruition, that "went on the journey broken" with this travel plug the subject certainly is not an issue. Once had a competing product which has been literally "smashed" me in a "soft" suitcase by an external force.
