It depends on the area of ​​application ...

I have the adapter for the kids my daughter ordered and retain despite small minuses:
- The sockets are in our flat mostly at the level of the light switch or directly below it. If the adapter is vertically inserted into the socket, then he blocked minimal the light switch, the one but still can operate.
- The indicator light seems a bit light, which I think is not so good, because the adapter is in the vicinity of the bed. But who knows, maybe it allows us to save the Nachtlich. ;-) That baby seems at least not to bother.

Otherwise, the adapter for our purpose is very convenient. We have the baby monitor and the bedside lamp connected to it. Since the socket with the adapter hangs so high that our child probably only Primary Age comes to it, we do not need additional socket fuse more.
