..and has been worth the price. After I had initially ordered me the adapter of Cable Matters for Surface, empfandich there from the beginning, the fit is not optimal (Surface is at the slot side chamfered), the plug stuck somehow just going in there, also fell before by yourself. That probably explains why and due to the active use (about half a year and about 50 days of use with assembly and dismantling), the plug was now completely broken, that there was no more data transfer, the connector head to Surface side hung loosely. The purchase of the original Microsoft adapter has proven itself in the first use: image transfer top, plug sits firmly on both sides, cap available for the Surface port - nothing wobbles.
