    Finally a working one-cable dock.

    Pricey but worth it. Plug-and-play with my MacBook Pro, drives two monitors at 60hz (I assume it can drive more, but I don't have that many!), supplies steady charge and has back-facing USB slots into which I've plugged my keyboard, mouse, and microphone. Works like a charm.

    Easy setup and functionality out of the box. Highly recommend depending on your needs.

    Out of the box, I had to update the firmware of several components. (Dell has a comprehensive firmware update utility available on their website) Easy setup and functionality is great. A less expensive alternative to the SD25TB5 depending on your needs.

    Had I bought it.

    I put off getting a docking station for years, but due to trying to travel with my computer and an auxiliary monitor I found I had to get something. I started out with a portable travel dock however, it did not have enough amperage to power the monitor and turned out being a mess. So I bought this. It works beautifully. I have an auxiliary monitor, auxiliary scanner, mouse, and my laptop plugged into it and everything works great. It is small enough to pack in my backpack and take with yet powerful enough to make everything work.

    Dock Fails to Negotiate Above 100Mbps Speeds And Needs Device Reset to Restore

    Recommend that you not purchase this item until Dell fixes the firmware. I am running this dock with a Dell XPS-15 laptop which is one of their supported devices as it does have a Thunberbolt 4 USB port. My main two uses of this dock is to have convenient access for a single USB-C to have the needed XPS power passed to the laptop and full ethernet speed of my network (2.5 Gbps). I continue to run into a difficult to reproduce issue that the network adapter keeps reverting to 100/100 Mbps. After verifying that all drivers and firmware on the dock are up to date, Dell told me a procedure to "har

    Great hardware, but a massive power brick and silent feature locks hold it back

    Overall, the Thunderbolt 4 Smart Dock is a remarkably capable piece of hardware. When it's up and running under optimal conditions, it handles high-resolution displays effortlessly and delivers top-tier throughput that really speeds up my workflow. That said, a couple of design quirks and quiet restrictions keep it from being perfect.First, the power supply brick is massive—it’s literally the exact same size as the dock itself. Trying to find a place for it under the desk or squeeze it into standard cable management trays is a real headache. It effectively doubles the physical footprint of the

    Provides flexibility and speed

    I've owned all the docking stations and travel companions that Dell has made including the original laptop dock that had a proprietary plug/bus on the bottom of the machine (my favorite). This Dock is really great too!The speed of the two Thunderbolt ports is really great and I've had Windows tell me that I should be using a Thunderbolt when I plugged into a USB-C port on the computer that was not similarly equipped. Its a difference maker.I have not yet used the dock as a power supply for any peripherals or the machine but it seems like a no brainer that I will forget a cord or have one die s
