The device works without any limitations, the cables are not particularly long, true, but in my rack of 160cm wide I can ferbinden all devices, even though they are exactly parallel each other at the outer corners.
The receiver has a super radius and is as big / small as a PC mouse. Would certainly hiding beautiful little, but now is not too wild.
The diodes have adhesive, this stuck to the IF points on the device and you're done. Everything runs smoothly and no delay!
What do you expect more for 17.- EUR?
Nothing, Weil does exactly what it is supposed to pass the signals and so, as if it were the original FB!
I can only advise, do not listen to the negative comments, and spend more for another set, Weil is my opinion not worth it!
Unless the cables are too short, or a mouse is great receiver too large, but otherwise there is no reason to pay more money !!!
In addition, you can easily test and return it so, if not like, before ordering More expensive ;-)
