Terrible quality for the price
Please, NEVER use the main switch, "uncertain" and sluggish contact, it rattles all over the place, and anyway, it fails after a few days. There is no switch for each port, and at this price, it is unacceptable. Anyway, the power supply failed after eight days, which was to be expected, it is undersized considering the number of ports. All hubs are pretty bad (yes, how can I explain that?), but this one, for the price, beats records of nullity. It is to be avoided! Nearly a hundred €uros down the drain in eight days. A shame. If you only plug in a mouse and a keyboard, it's fine, but a USB key and an external hard drive, it's already too much. Very angry.
