I bought the HUB to operate on a WD TV Live over 2 disks. Works like this: press the button of the FP is active and then press the button of the FP to be active. The activity of the ports of the active is displays sufficient and not too bright with a green LED. There are hardware buttons which snap. I think that's very good. Even a 2.5 "hard drive Works without additional power adapter. The Hub would have even an external power connector (no Neztteil, so rather what for crafting).
What has struck me negatively, but with me gets no penalty, is: The surface is not smooth, rather milky. Attaching Powerstipes to it somewhere "stuck" towards is very middle possible only on the lower side, as there sticks the label and is smooth. My experience with Powaerstripes was eigenltich always it sticks everywhere. But here it would have been almost impossible.
