BIGtec external 10-port active USB 2.0 Hub with Power Adapter White White 10 Port 10 x USB white from seller "lets-sell". Bad quality! USB connector can be plugged only häfte. Standing out halfway. On top of that the versions are without Anpressdrucck. All the versions show up as leierig and "wobbly". None of the versions takes thereby the plug on firmly. Due to constant Wakelkontakte. Even if the device is contactless on solid desk. Bad buy. Scrap goods. Must be told. Physical destruction of connected hard drives through these constant interruptions in the middle of writing or reading operation is therefore a "nice" side effect.
