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.

Working fine so far, with heavy use.
I've had this thing for a couple of weeks now, and have put it to heavy use. I've had 3 hard drives hooked up to it, along with a disc read/write unit with dual USB plugs, all working together with no problems.
