Rated 5 out of 5 by from Bit pricey but works! My wallet docked a star :P My laptop requires a min of 85W so this fits the bill and it does work on Linux. Tested with kernel 5.0.8.

Rated 5 out of 5 by from Amazing for Mac. *Verify your PC Hardware* This docking station is just what I?ve been waiting for, something to free up my AC adapter and allow a one-cable connection for everything. While it didn?t work for my USB-C equipped Ultrabook (make sure your hardware has a Thunderbolt3 controller; if it doesn?t, then all you will get is power) it worked flawlessly with my MacBook Pro, no drivers to install, no issues whatsoever! Construction is what I?ve come to expect; solid and well built, connectors are sturdy and there is a generous power supply with all the international plug ends. My only comment would be that there are no power lights; not on the Power brick or the dock itself. But that is far from a complaint. This thing is awesome.

Rated 5 out of 5 by from Does not work with Macbook Pro 15 Mojave 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!

Rated 5 out of 5 by from Doesn't work with Skype on a mac Good functionality but this is a business level product. Needs to work seemlessly with Skype.

Rated 5 out of 5 by from Solid Build and Nice Looking Device I have used this docking station for a few weeks with just my Lenovo T470 laptop and it works very well. I have attempted to connect other devices (that don't have Thunderbolt 3) but none of them work. The dock comes in a box about the size and weight of a brick. It was much heavier than I expected. Both the dock itself and the large power supply are equally heavy. The dock is made of medal and is very study and nicely built. The doc is about the same size as a large laptop power brick, which it comes with to power itself and the host device. I very much like the look of this dock on my desk. It has both a USB-C and USB-A 3.0 port on the front as well on the back it has these two ports again plus network, display port and headphone out then power, microphone and USB-C in. The doc connects very quickly when Windows has started. Only a couple of seconds and everything is working great. The docking station was able to keep my computer charged without any problem. My complaint with this product is it pretty much doesn't work with anything that does not have Thunderbolt 3. I tried using it with many other USB-C devices but nothing would work (charging, display, USB or network). I can get all of these working with single purpose USB-C adaptors but not this dock. This docking station does a very good job and looks very nice. It will likely replace every docking station in my office at some point in the future once all laptops support Thunderbolt 3.

Rated 5 out of 5 by from Power Supply is VERY noisy 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!

Rated 5 out of 5 by from Love this little thing! Use it mainly with my Macbook. Tested with a friend's Dell. In both cases, it just worked. Small, flat, hardly noticable. Feeds power through just fine, drives 4k via DP without an issue. Added 2nd HDMI monitor via adapter cable, and that was no issue either! Sometimes on the Macbook, after coming out of sleep, I need to disconnect the dock and reconnect, and then all is well. But it's not consistent, and not frequent. What I'd like to see is Mac compatible docks that have an option in the driver to tell OSX to disable/dim the built-in screen. But that's a wishlist, not a fault of this little beastie. Power pass through is appreciated, as I can leave my adapter in the bag, drop the computer on the desk and connect ONE cable. Would like to see an additional USB-C and USB-A on the front of the dock, as I tend to connect a thumb-drive and charge my phone, but I can work around that. Just a 'nice to have'. If there was a way to make this backward compatible with TB2... THEN it would be perfect. :) Overall though, SOLID build, decent port placement, great size, and near flawless performance (other than the reconnect/sleep thing I mentioned). I received this product in exchange for an unbiased review. And have already purchased an additional one for the Mrs.!!

Rated 5 out of 5 by from Best one out there, but... 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!

Rated 5 out of 5 by from Mostly good, but problem with ethernet Use this with MacBook Pro 13 (2018 model). Everything works nicely except for ethernet. I get to choose Thunderbolt Ethernet on the Mac but do not get any IP nor can us it by assigning my own IP. My switch sees the device, and the hardware handshake is OK. (green light on) If I put an Apple USB->Ethernet dongle in the USB-port on the Dock the same ethernet-cable immediatly work on that connection. But on the internal ethernet on the Dock it does not. Mac OS High Sierra 10.13.6

Rated 5 out of 5 by from Nice solidly built thunderbolt 3 Docking station What a great little dock! So the first thing you will notice that that this dock has some weight to it. I have tried some competitors docks before and some are much lighter. Now I prefer the fact that this has some weight and I found it helped to keep all the cables etc where I want them and not where the cables wanted to go. This dock offers multiple thunderbolt 3 ports, Displayport, Usb-3.0, ethernet and audio in/out along with power delivery. I tested this with my MacBook pro and found it worked like a charm. I tested with my external monitor and had no issues at all. Now I could not test at 4k as my monitor does not support it. But at 1080P this unit worked perfectly. This is a great options for people who want to leave all the cables hooked up and just plug the laptop in and off we go! I would recommend this unit to anyone looking for a well built and solid dock. Far better then most of the competition. "I received this product in exchange for an unbiased review"

Rated 5 out of 5 by from Makes me appreciate my Mac 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.

Rated 5 out of 5 by from Some problems It worked great for 2 weeks for my Macbook Pro. USB devices stopped working after 2 weeks with the dock. Power delivery and displays still work. Now I need a separate dongle for my USB devices. Might try to return this device and get something else that works.

Rated 5 out of 5 by from Power delivery dock all in one! I needed a dock instead of unplugging and plugging back in the cables everytime I needed to take my notebook with. This Thunderbolt dual 4k docking station from StarTech has surpassed my expectations. The quality metal build and compact size is just what I was looking for. The grey color also matches the Apple MacBook. I received this product in exchange for an unbiased review.?

Rated 5 out of 5 by from Great docking station Been using this docking station for almost 4 years. I have a Dell XPS 15 as my laptop and I have 2 Acer 4K displays attached as well. I also recently added a Lenovo to the mix and used Microsoft's Mouse Without Borders program (free). And my mouse and keyboard work as expected on all 4 monitors (2 laptop displays, 2 4k displays). No issues at all setting this up. Worked as expected right out the box. Not sure what the issues are that others have. I would definitely buy this again and recommend it to anybody that wants to attach 2 extra monitors to their system.

Rated 5 out of 5 by from It has Intel network chipset! I use the advanced Intel functions like teaming and VLAN, so I need a docking with Intel chipset. This dock has that, and it works like a charm! Unfortunately the dock has issues with running my Philips 4K monitor @60Hz, but it works @30Hz. I've used StarTech support, which could not solve my problems, but they had a workaround that I will test. They were very helpful and skilled.

Rated 5 out of 5 by from DOCKING STATION Been using it for 3 yrs I don't have any issues with it, as long as you use what you were told works, i use a Samsung 4k screens with an XPS thunderbolt 3 cable and i load the latest software i never had an issue, i,m not sure what some guys are running, the cheaper screens are the issue, not this device or maybe the computer or cable.

Rated 5 out of 5 by from Doesn't work properly It is unfortunate that this dock will just not work properly. I have tried everything to get the network and video to work on this thing with no luck. I am using it with a newer Thinkpad Windows laptop that definitely supports this dock. Disappointed.
