1 star because it does exactly what's advertised if you scrutinize the listing, but what it does is so mind numbingly stupid nobody would assume it's this poor of a product. It comes with a stand alone power input, but to use it properly you need an additional USBC power supply to feed into it, and oh yeah also most of the USBC ports deliver low power, and the USBA ports deliver no power. This is like a weird peripheral stuck in a time warp torn between 1998 and the modern day. Nobody is asking for this and the subtlety of how dumb this design is is reflected by the "Frequently returned item" disclaimer. Whoever product managed this needs to rethink their career

Worked fine.

Style: 8-in-1

When I tried to plug in our new backup hard drive, I got a message saying something like "USB power exceeded." Bought this, plugged it in, attached the hard drive, no problems since.
