I was using this with my M1 Mac mini, but I'm selling it, so I'm also selling the hub. It's made by Satechi and I think it's very easy to use. The list price on the latest Amazon site was about 10,000 yen (see photo 2), so I think it's a good deal. There are no noticeable scratches, but please understand that this is a used item before purchasing. (The color is Space Gray)
