However, I have two criticisms. The Funksteckdosen I've ever used, there are still on the device on / off switch. I miss this unfortunately in the set, which is a shame. So you always need the remote control.
My second gripe is that upon delivery all outlets are set to the same frequency, ie all outlets switch on and again with the same knob. Depending on the application that's perhaps even desirable. But the norm is certainly that you want to control the sockets separately. This means you have to remove a flap on the back and change the encoding of the can. Certainly not rocket science, but effort and thus not a true Plug and Play.
Conclusion: A good and cheap set, but with the 2 points of criticism from the top only a 4-star product for me.
