I bought the dock for a 4K monitor, but it wasn't usable with my laptop as I frequently lost the signal. Furthermore, the dock makes a very loud whistling sound (coil whine), especially when the video output is not on, which alone led to me returning the dock. I bought a USB-C to DP cable instead, which works well.
USB4
port equipment
Nice design (ports at the back and front)
fast SD card reader
Gets quite hot, the "holes" on the top are just for decoration, it's one solid piece of plastic. Cooling is only from underneath.
Can't do 4K 144Hz, the max I could get with DSC was 4K 120Hz
terrible coil whine
It amplifies the noise in the picture, probably poor workmanship, I don't know
Setting up a multi-screen display is a bit of a faff, and the dock sometimes cuts out when connecting/disconnecting.

I bought the device for a trial, currently the only one available with USB4, but unfortunately it is very poor quality, the picture has interference, the USB-C cable has no markings so it is not even sure if it is USB4.
image problems
the whole device is curved
missing USB4 cable marking

Sufficient number of ports (USB-C, USB-A, Displayport, audio jack. )
Input port thunderbolt 4, 4k at 120Hz works without issue
When I connect the monitor via the hub, the DDC doesn't work (can't control the volume and brightness of the monitor via the keyboard).

enough ports to connect anything
auxiliary power supply (5V/2A) for more power-hungry peripherals for NTBs without PD - one of the things I bought it for
4K resolution at 144Hz on Dell G3223Q
quality DAC - essential for me
The only thing that bothers me a bit is that it is made of plastic, but on the other hand, it is made of good quality and well processed, so when it is on the table, you can not tell at first glance.
