Processing: Well, Function: Unsatisfactory

The review title is in need of explanation. Why the function is poor, although the workmanship is good? For this, the manufacturer can not necessarily what. The adapter is very solid and gilded because everything is right. The problem with this adapter is that it is quite difficult. If you still infects a DVI cable and the adapter then plugs into the HDMI jack, for example a notebook, the adapter is levered downwards. Nevertheless, the signal transmission works perfectly, but whether the socket is good in the long run? I did not want to depend on it, and have therefore now bought a differently designed adapters.
