inexpensive usb3.1 gen 2 hub with PD
This USB3.1 gen 2 hub is well made, featuring VIA Labs controller (device id 2109:2822) and is made in China. It looks nice and performs according to the specs. I wish usb-c socket supported TB3/Alt DP cable to connect a display to it, but it is apparently made mainly for power delivery. I think the hub is a good value.

premium feel in the hand.
Can't really say whether it's that good or not elecronics wise since I didn't test it but it works like it's supposed to. Meanwhile, the housing oh man. It's premium. It feels like hard aluminum or something, very nice. Edges are rounded too with just the right sharpness like a macbook. Others would've been plastic. This is really nice for the price and if the specs really are 10Gbps, that's really good because most in this price range is 5Gbps.

Failed to support desktop PCs with USB 3.2 Gen 2 ports
Does not work with my HP mini PC with USB 3.2 gen 2 ports - when connecting USB portable SSDs to the hub. You won't believe it, but many USB 3.2 Gen 2 hubs only support laptops not desktop PCs (except hubs that have dedicated power supply for higher power USB devices e.g. SSD/HDDs) when connecting USB portable SSDs to the hub. We need a major fix from many of the USB hub vendors so these products can work with desktop PCs that have USB 3.2 Gen 2 ports. Workaround: Just directly connect the USB portable SSD to the PC instead. If you need more USB ports, pick up a good old USB 3.0 hub. They're working correctly with portable USB SSDs when working with desktop PCs. (You'd need a powered USB hub if you're connecting 2 or more portable SSDs - do your own calculation: 5V - 1A per SSD/HDD).
