Rated 5 out of 5 by from Fantastic little travel companion! Keep in mind, that this is TB-3. This is *NOT* TB-2 or USB-C. OK, the negative first: The built-in cable is WAY too short and not removable. Now to the good stuff! This thing is FAST. It just worked on my Macbook. Even driving dual-4k, transferring data via USB, and network, nothing seemed to slow down at all. It took some dings in my field bag, and got some dust and fuzz in there, but it never stopped working. Keep some of that "non-slide" shelf-liner with you and this little lightweight dock won't slide around either (being that light is a plus in my book!) I received this product in exchange for an unbiased review.

Rated 5 out of 5 by from Almost fully works with Mac I was able to connect two 4K monitors and run both at 60hz on a 15" 2016 MBP via Thunderbolt 3. The USB port works but I was not able to get the Ethernet to work. I checked the downloads section and could not find a driver.

Rated 5 out of 5 by from Excellent 4K Monitor Mini Thunderbolt 3 Dock I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use on my Microsoft and Apple devices. This unit is bus-powered, so there is no external power required, which is a great feature. The attached USB-C cable has an extended length of approximately 8 inches, which allows for flexibility in physical set up. The unit installs quickly and is compatible with a variety of operating systems, which I tested. What is Included: 1 - Thunderbolt 3 Dock 1 - Instruction Manual Note: “I received this product in exchange for an unbiased review.”

Rated 5 out of 5 by from One annoying trait This product generally works as expected and I've rarely had any issues except for one that unfortunately crops up daily. I have my MacBook Pro connected to two external monitors but have to disconnect many times a day when I take the laptop to meetings. Upon returning to my desk and reconnecting the dock, the screens may switch (left screen is now the right screen). It happens at least 50% of the time and I have go to my display settings to re-arrange them. I can't isolate what causes it and I think it's just a race situation. Whichever display the dock recognizes first is just assigned a random placement. Frustrating productivity killer.

Rated 5 out of 5 by from Problems with macOS Mojave and the DisplayPorts I bought this dock to use with my 2018 MacBook Pro 15", specifically for the dual DisplayPorts to connect my two 24" ViewSonic monitors. The Monitors work perfectly with my Windows 10 notebook using the DisplayPort to DVI cables. But, I can't get the MacBook to detect either one of the monitors through either DisplayPort on the dock. The USB port, and ethernet port, on the dock work flawlessly. It's definitely fast. I just wish the DisplayPorts worked.

Rated 5 out of 5 by from Works as advertised Been using it for 6 months without issue, with a 2018 15" MacBook Pro. Not likely related to this product, but I found that I had to connect my third monitor on the other side of the MacBook, while using a USB-C to HDMI adapter. Might be a limitation of the MacBook that I haven't found documented anywhere else, for the number of displays it can output per side of the laptop.

Rated 5 out of 5 by from USB port stopped working The USB port began to be unreliable (sometimes would start working after disconnecting/reconnecting the dock, and has now stopped working altogther.

Rated 5 out of 5 by from MacBook Pro M1 (2020 Battery Drain The hub drains the battery much faster when this hub is connected. Based on the time remaining estimates provided by the Activity Monitor the battery is max 8 hours with in plugged in versus 18+ hours without it plugged in. The only thing plugged in to the hub is an Apple keyboard.
