The product is very small and allows me to store it easily in the bag of my Asus Transformer Book T100, so I can make a movie, my music, etc ... on any screen, without having to follow a HDMI cable everywhere, that would take much more space ... (Provided that the person was still an HDMI connected device on its TV, this adapter is not sufficient in itself) Nice little details, entry (female side) is at right angles to the output (male side), avoiding twisting that would force a bit on the socket of the connected device: when HDMI is laid flat, the microHDMI jack is placed on the edge, and vice versa
