Also I let myself from the reasonably good reviews here on Amazon dazzle and promptly was disappointed. Nothing works as it should. Time goes sometimes not. The angle at which you can use the Extender is very small. Furthermore, the cables are clamped into the transmitter diodes only (with so-called. Print contacts) and not soldered, which may be an explanation for the unreliability of the device. Only you do not want to deal as a client with such a nonsense. The stuff is supposed to do just that for which it was designed. That's here as I said not the case. I have no desire to return the part. It comes in the trash where it belongs.
