After all flawless operation (tested on Galaxy Note 3), the cables are long enough to be connected everywhere and there is no need adapters wacky as some other cables: one branch and it works!
I plugged in several HDMI outputs and only my amp Pioneer VSX-923 only happened not select the HDMI video because it is only compatible MHL 1.0. By removing the control of HDMI devices from the amp and everything works flawless Full HD (1080p)
Also be careful because if you use a HMDI / DVI adapter (for connecting to a PC screen, for example) the fact that the MHL adapter is limited to 640x480. This is not a limitation of this cable in particular, but the standard MHL ...
In short, impeccable product does what is asked and very fast delivery.
Very Satisfied.
