2 out of 5 stars
Not what I was hoping for from the description.
Unfortunately it is not possible to use 2 monitors separately, only duplicate.
According to the manufacturer's page: When using two monitors at the same time, both monitors have a resolution of 1080p and display the same content.
Unfortunately not usable for the home office.
However, the quality is very high.
Pros: Good quality
Cons: Expanding the screen is not possible

--> I wanted to connect a 4K screen via HDMI. It didn't work because the hub only provides this resolution at 30 Hz. I then only had 2K with 60 Hz instead of UHD. I would clearly advise against buying it if the hub is to be used for a home office or similar. It is better to buy a more expensive docking.
