I have a 24" iMac and annoyed about the USB ports on the back. Looked for a hub that looks integrated from the front. Satechi ones are $90+
Found this for $19 + ~ $10 delivery.
Price matched at Officeworks today for a grand total of $27.50.
Fits my iMac quite well.
Not able to fit Studio Display.
Surely you want a Thunderbolt dock rather than a USB C dock.
