Affordability while being affordable
It works well, even better than $400 priced my previous TB4 hub at such a descent price.
Even if I have some issues when I connect this to more than three usb devices at once, but the price of this item justifies its functionality as good as useful.

Works well
Sometimes gets a little warm, but otherwise excellent. First USB-C (10gb) hub I've had that regularly handles 3 USB C drives without issue.

Works with Viture XR Pro glasses!
So it is rare that I post about a product the same day that I got it but this USB-C hub did exactly what I wanted it to do!
A little background, I recently got a pair of Viture XR Pro glasses and I am using them with a Samsung Galaxy S23 5G which has the benefit of Samsung DeX. The goal was to be able to use USB-A dongles for wireless keyboard and mouse in addition to charging my phone with a power delivery port and using my glasses.
Long story short, it works flawlessly and I still have 1 USB-A and 3 USB-C ports to use!

Works well. Compact.
Works well. I have a camera monitor and my MacBook Air attached to it. I wish the cable were longer so I could push it all to the back of my desk. The cable is about 6 inches.
