It is good, but don't expect to connect particularly power-hungry devices to it, it only works for USB receivers.

If you connect something heavy like a simple flash drive, it doesn't have enough power and disconnects it, which can damage the flash drive.

This only applies to USB 3 flash drives, though, there is no issue with USB 2.

I had three different USB receivers connected and active (1 Bluetooth and 2 for two different mice) and 1 USB 3 flash drive. Every time I tried to do something with the flash drive (even a simple folder deletion), it would immediately disconnect and reconnect, something that never happened with a USB 2 flash drive.

Although it has a port for an external power supply (micro DC Jack), it does not come with one, so maybe if you have one to use (at least 5V 2A), you won't have issues with USB 3 power-hungry devices, and I think it will be fine afterwards because from what I saw when I opened it and looked for its chip, it is one of the best.
