So: The Ansmann Energy saving socket ordered, briefly consulted the very clear guidance and after a few minutes I could be stated: It works. The "learning" of the individual standby consumption was easy to do and the shutdown of the equipment works reliably. I have incidentally not measure: I trust currently the manufacturer's statements that these can actually completely separates the device from the mains (after all, you can hear a distinct "click" of an internal switch when switching off).
Very handy is that the red button indicates by flashing when the device detects the standby voltage and turns off soon. By about 1.5 meter long lead, you can place this button very good.
A useful side effect: can While "normal" switch also accidentally off times unintentionally (who has not yet happened to the computer at the power strip with a switch?), Is not possible with the Ansmann-box: The button is used solely to turn, accidental operation during operation has no effect.
I have calculated that I currently pay about 10 euros per year just for the standby power consumption of your computer, monitor and speakers. The acquisition of this box is worth it after not even a half years for me. Whether I the environment really do so something good, I can not judge correctly, because this can has and certainly in the production ("Made in China"), on the transport and at some point in the disposal (not household waste, but electronics Scrap) consume energy.
One point deduction, there is, because it is apparently not intended to fix the red switch somehow: The first is now somewhat inelegantly around here.
Edit: I have my review Unfortunately edit and remove points: The device has already failed twice the service and just want to no longer automatically turned off. Once it has been replaced by Ansmann me, but the second time I had no desire to move around the broken part. Meanwhile, it has even the mistakes, despite ongoing equipment "accidentally" disable. In computer operation so even dangerous, because I never know if not lost by current draw my data in the next moment.
