Works great. I used to plug in a mouse, an external hard drive, and an overhead Nikon digital camera for historic digitization of documents and books. It small and compatible and there were no connection or power problems. It feels well built and sturdy and the cord connection to the device is strong and flexible.

Great for retro emulation!

Got this for a retro emulation setup. Worked great. No issues whatsoever. Works on apple as well. Its a basic usb hub, but doesn't feel cheap. Got it on sale, which made it even better!

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.
