Dell ThunderBolt 4 Dock (WD22TB4), Black

Does exactly what its supposed to do. Port replication and high-speed charging on compatible laptops. Dell Docking station - and I assume other vendors solutions - are just an elaborate adapter to break out your laptops ports to provide more flexible connectivity options for network, video, sound, USB peripherals, etc. Anyone purchasing this because they think it is an external video card that will have or add on to the capability of their existing computer video card or other hardware is seriously misinformed and this is not the fault of Dell or anyone else. Also, if your device does not have thunderbolt 4 and you have a lackluster experience with this device, keep in mind running it in USB-C mode will only yield the capability based on the bandwidth of USB-C and not Thunderbolt. Long story short - you need to understand what you are buying before you buy and give a negative review.
