Product that promises much, rather disappointing quality

I have had good experiences with Anker (external battery and charger 5 USB ports) so I expected a lot from this hub. Indeed, the product seems finished, the packaging is treated as always with them, and specifications are salivating but ...

- Compatibility with some peripherals seems risky (not always recognized by the OS when a device is connected)
- Electric Sizzling time to time on taking magnetization on the hub that makes me think that the product does not really last very long

In short, the experience is not up to my expectations.

-Edit-

I refer the hub. It's really very, very poor quality. Unexpected result: a contolleur USB3 now seems grilled on my PC (the ports on the map even mother no longer respond). A strange coincidence is that it is the controller on which was connected the hub. Very very disappointed and really not a product worthy of Anker. And not a product that is 45, for sure.
