The build quality is very good, because there is nothing wrong. (Adapter August 2014 at "lets-sell!" (Amazon Marketplace) bought). But: The Micro-USB connector of the adapter is rectangular trapezoidal instead. One wonders every time, like rum you should insert the micro-USB connector. It's frustrating. With USB connectors you have anyway to take care that they put into it in the correct direction. That it is more annoying, proves this adapter. To make matters even worse: The Micro-USB connector is rotated relative to the mini-USB connector by 180 °. If the plane of the mini-USB connector is above the plane of the micro-USB connector should face downward. In other words: If the USB logo is palpable on the top of the adapter, you have to feel it on the bottom of the micro-USB connector. Very "practical" if you want to attach the adapter in dim lighting. ;)
