Previously I was using the Apple USB-C/HDMI - USB Video adapter and a similar device form Choetech. Both worked, but with daily plugging/unplugging it literally got to the point that if you knocked the desk, the screens would lose their image for a second or two, and occasionally stay off, and would require plugging/unplugging/wiggling etc. I saw the review of this on 9to5Mac and pretty much immediately ordered one. It has been about a week now, works perfectly, everything permanently connected to the CalDigit, and one cable to the MacBook. Even "jiggled" the plug and no disconnect at all. The only thing I a not keen on (but not a deal-breaker and I knew it before purchase) is you still need to plug the charging cable directly to the MacBook, but then I guess technically that is better anyway (no 3rd party devices in the middle). the only other thing i did notice, I use a full-size Apple USB keyboard which has two USB-A sockets, you might get some issues with them if you plug in something to charge (or that needs power) with the keyboard connected to the USB2 on the CalDigit, but when connected to the USB3, everything seems fine. Again, not a deal-breaker, but wanted to let people know in case they thought (like I did at first) that something was wrong. All in all great product. just wish I could buy another one and have four screens (but my Macbook won't handle it) Review: Great value for triple display 2019 16" MacBook - I purchased this after trying some other less expensive options for connecting dual monitors to my 16" MacBook Pro. I have been able to run the following display configurations: MacBook display, a 3440x1440 display @ 100Hz, and a 1920x1080 display @ 120Hz. MacBook closed (so no MacBook display), 3440x1440 display @ 100Hz, and 1920x1080 display @ 120Hz. Confirmed framerates via the Test UFO site. Haven't tried only running one of my monitors but I assume that will work fine considering I'm able to push three displays. Ethernet is working as expected, as well as the USB 3.0 port for both power and data. The hub does run fairly hot, but that's to be expected. Compared to some more expensive hubs, if you are like me and need less ports, just need ethernet and 2xHDMI ports, this is perfect. I have tried some of the options more around the $70 and they haven't worked. Spend a little more and grab this. ## Features - [GENUINE THUNDERBOLT 3 40Gbps] Portable, Bus Powered, Aluminum Dock with built in Thunderbolt 3 cable - [DUAL 4K EXTENDED DISPLAYS]: Connect up to two 4K@60Hz (4096 x 2160) displays - [FULL PERFORMANCE USB 3] Type-A USB port supports 5Gb/s transfer speeds and 900mA of power, convenient for connecting your USB peripherals and storage on the go - [GIGABIT ETHERNET] Unlock full network performance on the go through a wired connection.

I have one set up with two monitors, wireless keyboard, webcam, and wireless mouse. Just plug in my PC or MAC laptop and everything works flawlessly. I have had the CalDigit hub for years and just purchased a second one for an additional home office. I have tried other hubs, but was grossly disappointed-this one is the way to go. ## Frequently Bought Together - CalDigit Thunderbolt 3 Mini Dock - Bus Powered, Non Charging, 40Gbs, Dual 4K Display, USB 3.0 & 2.0 and Gigabit Ethernet LAN for Mac and PC, Thunderbolt 4 Compatible (Dual HDMI 2.0, Black) - Apple Magic Mouse: Wireless, Bluetooth, Rechargeable.
