It WORKS! I'm Back at Work. Thx to Apple for support and Amazon for fast delivery
I am thrilled to report that the Anker USB C Hub with Ethernet fixed a dire problem that nailed me when I switched from my maybe-20 year old dying wired Apple Extended Keyboard to the Macally keyboard comparable (with USB-C connection). I have a 2023 MacBook Pro 14", a lovely workhorse, with 3 USB-C/Thunderbolt ports, a MagSafe power port and an HDMI port (with, it turned out, limited ability to handle UHD displays, so useless for my desk setup). It turned out my old Dockteck hub with ethernet didn't have thunderbolt capable USB-C ports, so my new MacAlly keyboard connected to that hub stopped working. On top of that, as I swapped with my Logi webcam, it also required a trickle of power the Dockteck hub didn't provide. As soon as I figured out what the issue was, I read up on several multiport adapters with ethernet, and it seemed that either I would be stuck purchasing WAY more than I needed, adding another bulky (annoying!) device on my desk surface and costing me close to $200. This seemed crazy, so I called Apple Store support. The only Apple Store multiport adapter was useless to me (and also $80) because, of all weird things, it had only ONE USB-C/Thunderbolt compatible port among 8--most ports were legacy. (Ugly too, just saying folks don't HAVE to make devices ugly!) The Apple Store rep, in one of those brilliant customer rep incidents, understood quickly the challenge, said Apple Store didn't have anything that would work for me, but SHE KNEW SOMEONE (ta-da! better than AI!) who would know and could recommend. Three minutes later she said this Anker device would work. I had it in hand by 6pm same day. So this is not just a rave for a solution that WORKS, but also a thank you to the great support from Apple to get me back to work fast. And Amazon for getting the item to me fast too!

Great as long as you know its limitations; runs warm; monitor settings may need to be changed
I reluctantly gave up MagSafe and joined the USB-C future when my employer issued me a new 2019 16" MacBook Pro. Searching for a way to connect my various peripherals I settled on this hub as a reasonable way to connect a 4K display, pass power from the laptop charger (albeit not the full 96W; macOS reports 79W after hub losses—good enough most of the time), connect 1GigE, and provide a few spare USB ports and occasionally-used SD card slots. I've learned a few things: A port that looks like USB-C does not pass video unless it is a "Thunderbolt" port (look for the lightning bolt logo, apparently); connecting a USB-C-to-mini-DisplayPort adapter to the USB-C port on this hub did not allow my monitor to work. Lesson learned. The HDMI port did work, and did pass 4K@60Hz, but only after I adjusted my monitor settings. At first I was convinced either my HDMI cable or this hub were defective, because macOS would only allow me to select 4K@30Hz. I have an LG 4K display, and from reading forums, one must enable 60Hz in the on-screen display menu before the monitor will tell the computer it is capable of displaying 60Hz video. For my monitor, that meant changing "Ratio" in "Quick Settings" to "Original" (it defaulted to "Wide", with a separate configuration for each port), as well as turning on "HDMI ULTRA HD Deep Color" from "Picture" -> "Picture Adjust." After I changed those two settings, 60Hz was not available until I unplugged the HDMI cable from the hub and plugged it in again. After that I had buttery smooth 4K video at 60Hz. The hub works as advertised, at least for my configuration. The 1GigE port works well, and is equivalent to a direct USB-C to Ethernet adapter I tried. It does run warm to the touch as other reviewers have reported. That's not problematic, but I'd prefer it pass the missing 17W to the laptop rather than dissipate it as heat. Time will tell how well the hub holds up, but for now I'm happy. In summary: if you have a new Mac this hub will likely work for you, though you may need to adjust your monitor settings.

Older flash drives might not work.
Port labels are too faint to read easily and the PD out port isn't labelled (I suppose they thought it was obvious since it has a fixed cable).
The USB ports are speedy except it won't recognize any of my several SanDisk Cruzer Glides. Others flash drives work okay.
Works great as an iPhone USB C to TV HDMI converter.

Worth every penny
Size: USB C to Ethernet Adapter
This adapter provides a stable, hardwired connection when Wi-Fi is not fast enough for heavy law school research. It is strictly plug and play, requiring no software installation. The weight is negligible, making it easy to keep in my bag for campus. Given the excellent build quality and consistent functionality without any drop-offs, it offers solid value for money. It’s perfectly versatile for numerous uses (keeps me from having to use like 3 other dongles)
