very poor workmanship and function

I have bought this stroke me four months ago and from the beginning had problems with it. Not every port worked right away. You had to try around until wiggle etc. In addition, the processing is very bad, the contact points in the ports are all different heights, so that in some first Fingerspitengefühl something you needed anzuschlißen to the desired USB device.
For several days, the part does not at all more and has even put my USB ports paralyzed. Only after restarting the computer to recognize the connected devices again.
Conclusion: never again
