Adapters are too heavy.

First of all: The adapters operate electrically properly.

These plugs are due to their size and the material so heavy that I simply fell out of the Australian outlets of its own. I always had to put a book. The Australian doses not as a self-sustaining as deepening our Germans, so this adapter does not always hold its own. I recommend a lighter plastic adapter, rather than this heavy rubber part. Incidentally, you have to grab the weight with in the suitcase.
