Ripped off by an Amazon seller.
The 7-port Thunderbolt 3 hub for the MacBook Pro arrived today. I tried it immediately, the HDMI, two Thunderbolt 3, microSD & SD card ports work as advertised. But the bastards have skimped on the USB ports. The are coloured blue & advertised as being USB 3·0 but it's shown in System Information app that they're only USB 2·0.
Filthy whores.
Left scathing review.
At least the colour matches that of the Mac.
