The product is terrible. Firstly, the cable gets frayed and pulled out of the plastic along with all the ports. Secondly, it constantly disconnects with more than two devices connected. Avoid it.

When you connect the devices, it seems like they are not properly connected inside, but they are actually securely connected and do not disconnect.
Also, pay attention to the port you connect it to. I connected it to one and it disconnected when I plugged in multiple devices, while with the same devices in another port, everything was fine. Obviously, this was a problem with the port I used and not with the product itself, which was working fine.
Overall, it seems good from the initial tests I did with a keyboard and RGB mouse and microphone, but I haven't used it at all for data transfer.

For me, it only works in USB 2.0 mode. When I connect a new device, everything disconnects and reconnects. Tragic.

Useful hub for mac users, it seems to be well-made and performs well. Be careful not to have it constantly plugged into the macbook as it may scratch it.
