Funksteckdosen with barely reach = almost meaningless

Due to the 'exceptional design' I wanted to use this inconspicuous radio set for devices with euro plug, for Aufhübschung my existing installations (various IKEA, Home Easy, ELRO and InterTechno adapter plug or flush mounting switches - all of these usually work through walls and also 10m away from remotes or TellStick.net Gateway still problems). When HE800S is also a ELRO device, such as the manual shows.

That the test of the first plug after only 50 cm (!) Was concluded with the reach, I could not at first believe.
Remote control and battery are in order, because the gateway in the next room can receive the signals from the transmitter.
The core problem is apparent at intermediate connector HE800S or its reception.
The second connector comes with me now (after some time in the socket, but should have no influence) to just under 4 meters in direct line of sight. But he turned at that distance is not always at the first operation. If there are obstacles, there is my first experience after little chance for reliable operation :-(
Because the set is also not taxable to the TellStick (my specific request), it will be exchanged.

Positive
+ Flat design, Euro-jack down
Negative
- Doubtful reach For me an additional negative
- Incompatible with TellStick

PS: I have the set (in this case due to the critical reviews) locally bought at the hardware store for 15.49 - facilitates the exchange immensely.
