These three criteria were important to me and are all satisfied. The instructive reviews were for the selection again crucial and I'm happy with the choice. The extent to which there are mechanical problems in the long run remains to be seen - to me it seems to be a general problem with the Micro connectors, either keep them tight (and destroy by leveraging the case jack or a whole tablet) or are too loose and lose in the slightest movement of the electrical contact. These connectors seem to date represent a good compromise, download much faster than other cables from me and 2 meters is an ideal length for me.
