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.

Do you need a powered hub instead?

NOT powered. My bad, I didn't look closely enough. I need a powered hub.

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.
