What I also like very much is the option of slaves (in my case audio components) to be able to simply switch by Rocker, just without the Master (TV) is in operation. In practice, this means in my power strips version to press the switch from "Automatic" to "Manual". The process even my 4 year old daughter get along right away.
Unfortunately, in my version, the LEDs and the lettering for Master / Slave Power have been reversed. This fact is basically just waste and therefore acceptable by me. For this price (just under 20 EUR excluding shipping) I'm with the product so far completely satisfied. The circuit of the slave is based on the (manual) adjustment of the threshold absolutely reliable and clean. If you encounter any technical problems with this power strip in the course of time, so I will report!
