Arrived very quickly to UK, good value for money and it works well as a basic hub for my M4 iMac - no thanks to Apple! Their Thunderbolt system is not backwards compatible with older USB devices but this hub solved the problem. A 30watt USB power supply is being used to power the hub through the PD slot and it drives a 1TB hard disk external drive without any problems.
Cannot comment on HDMI as I don't use it but the SD/TF card slots only read one or the other, not both at the same time.
