My laptop requires a min of 85W so this fits the bill and it does work on Linux.  Tested with kernel 5.0.8.  Remember to add the dock to approved Thunderbolt ACL list.

Bit pricey but works! My wallet docked a star :P

I bought this to use with my Macbook Pro 15, 2017.  After reading the issues that primarily involved (Windows) drivers and cabling, I paired it with a Nekteck TB3 cable to the dock, and a Club3d CAC-1066 DP cable to a ThinkVision L27q (4k, 60Hz).  Plus a Cat6 cable and a Logitech wireless USB receiver. Audio jacks are recognized and work fine.  Can't speak to dual displays, but if you do, watch what HDMI port you use on your monitor, not all of them support 4k60Hz. (Ran into that with a Samsung 4k monitor + Radeon Pro card.)

Here's my gripe, and I'm not sure where the breakdown is:  The USB 3.0 ports on the monitor do not work unless the monitor is driven by the USB 3.0 connection, not DP.  When both DP and USB cables are connected, the MBP thinks there are three displays, even though I only have one selected (obviously).  Maybe its a firmware issue with the L27u, maybe the Dock, maybe the MBP.  Not sure.  This means that I can't plug in my factory USB soundbar, the Logitech receiver, or anything else into the 4 USB ports on the monitor. And since there's only 2 USB 2.0 ports on the dock, it limits the number of devices I can use at once.

Just something to think about, but overall its a very good dock. Looks great on my desk too!

Best one out there, but...

I love the simplicity of this device. I plug in one USB-C connection on my Mac and it supports two monitors. Everything works as expected. I just have one complaint (let me know if you have a solution). When I plug it in in the morning, sometimes it ignores my screen organization. It will put my left screen image on the right monitor and my right screen image on the left monitor. I can usually fix it by unplugging it and plugging it back in, but I'd like the screens to just come up correctly all the time.

Great but...

Atha

I was provided this dock by my company to handle the external monitors they provided.  I am unable to use this with a DisplayPort cable from my monitor, the image becomes unstable.  I am able to utilize an HDMI cable with an adapter but each day I have to unplug and replug the adapter.  I have tried multiple different active adapters and they all have the same issue.
So the dock works, but there are better docks out there for the same price point that function flawlessly.

Displayport Does Not Stay Active

Malcolm

Purchased to work with my HP Spectra x360 15in 2017.  It does not work with two monitors out of the box with the supplied drivers. Windows 10 Pro 64 is up-to-date, computer is up-to-date with all Intel and HP updates..  I am waiting for a reply from technical support.  Everything works perfectly when I plug in my Mac.  So I know it is not a cable issue. It is  my Windows 10 work computer I need it for.  It works with 1 monitor attached.  I can get two external monitors to work if I plug one into the computer's HDMI port, but that is not why I purchased it.

Makes me appreciate my Mac

Matt

I have had this dock for about 5 months. I have a 13" Mac Pro connected to 2 additional monitors. Most of the time, I am able to plug my laptop in and everything works as expected. About once a week, I have to reset the display orientations because they get mixed up - it would be nice if the settings remained the same each time I plug it back in. I wouldn't have taken the time to review that bug if that was my only issue. About once a month, I come it, plug my laptop in, and only 1 of the monitors will work. It's never the same monitor that works, each time I connect and disconnect, it's a gamble on which one will connect. I have tried EVERYTHING, from resetting settings, changing wires, using every sort of monitor connection, and nothing has ever resolved it. Randomly. the second monitor will just start working again. Very frustrating, spending hours trying to get a monitor to work instead of getting my actual work done.

When it's working, it's great

Beware: This dock does NOT support dual monitors.  I have a 2019 15" MacBook Pro running macOS 10.14.6 Mojave and two HP ZR2740w monitors (native resolution 2560 x 1440 @ 60 Hz).  When I plug one monitor into the dock and one into the computer, they both work.  But when I plug both into the dock, they do not work.  The mouse freezes every few seconds, and I can not use the computer.  Unacceptable.

Does NOT support dual monitors

Had this unit for a few months and all was well until I networked it with a few other computers in my studio. AWFUL noise and static/crackles/whining coming through my audio monitors. Started trouble shooting to narrow down the culprit and its the cheap power supply on this dock. If I switch to the supplied Apple power supply, all is golden but I have to plug all my devices straight into the MacBook Pro which defeats the purpose of the dock. If anyone has any ideas how to fix this PLEASE enlighten me!

Power Supply is VERY noisy

Brian

Got it to connect to a Dell Displayport to my Macbook pro 15 running the latest Mojave OS. The power via USB-C works great. Unfortunately, nothing else does. The USB-C to Displayport is not recognized at all - the Macbook gives an error that the thunderbolt device is not supported. My display also has an HDMI in, so I used Apple original HDMI-USB-C adapter and still the same error. I then connect the display directly to the Macbook and it works flawlessly, including sending the power through the Apple adapter. So at this time, the dock is acting as a super-expensive power supply!

Does not work with Macbook Pro 15 Mojave

This dock is more or less working as a thunderbolt dock - my MacBook is connected to external monitor (5k @ 60Hz), USB stuff and charging.

However - it creates a squealing noise (most likely from the power supply) that is absolute torture that singlehandedly makes $5000 of laptop, monitor, and accessories awful to be around.

In this state, this dock literally has negative value.

Good in theory, torture in practice
