Anker wins again.
Worked well for usb hub but hdmi was not reliable. Disappointed because usually Anker products are good quality. UPDATE: Anker voluntarily offered a refund so my faith in Anker has been fully restored.

Perfect with a MacBook
The Anker USB C Hub works great with my MacBook Air. I paired it with the Anker 100W MacBook charger which plugs directly into the USB C Hub so I only have to plug in one cable like a true docking station. My Apple MagSafe charger stays in my briefcase so I always have a charger when I'm away from my desk.
I also plug in my external monitor and an external hard drive.
I highly recommend this product!

It's a good USB-C dongle, but it's not magic!
Honestly, this is an excellent USB-C hub if you just need a couple more USB ports or an extra display output. I've now purchased two, one for my Razer Blade for over a year, and one for my wife's Surface Pro 7. On both systems, it was very much plug-and-play. As soon as it was plugged in, Windows recognized it, and we were ready to go.
At home I use it on my Razer for an RGB keyboard, wireless mouse receiver, wireless headset receiver, and HDMI output to keep my desk area looking clean, and be able to connect/disconnect all my extra peripherals with one cable. While traveling (pre-COVID), I used it for it's RJ-45 jack and hooking up my travel peripherals with one cable. It worked great for both, no issues to speak of.
My wife uses it on her Surface for pretty much the same purpose, which is really nice to have considering the Surface's lack of outputs. It works great on her device as well.
The hub is lightweight, feels sturdy, and works as expected. You just need to make sure your computer's USB-C ports support what you're trying to do with it. This hub won't magically turn a USB-C port on your computer into an HDMI port or RJ-45 jack unless your computer supports it, so make sure you check your ports specs in the manual or on the manufacturers website.
Only downsides are that it can run a little warm while using it. But considering it's passively cooled, as long as you're not covering it up, it should be fine. Also, a little personal gripe is that the cable feels a little too short. But that's just me, and I make do just fine.

Awesome little dock
The build quality on this is exceptional for the price. Really solid, mostly metal with a nicely braided cable. Really good for the price, I bought this at $35, and I would have paid more if I knew what I was getting. Way better than my old cheap plastic dock that broke. This is the second Anker product that I've bought (the other one is a battery power bank), and both products have exceeded my expectations. I will update if anything goes wrong with it, but so far this has been a really good buy...
UPDATE: After using it for a little while longer I have noticed that when the ethernet cable comes unplugged if I just plug it back in, my laptop won't recognize the ethernet connection. The lights will still turn back on on the port, but my laptop won't connect with it. In order to fix this, I have to unplug the dock from my USB-C port and plug it back in. After that, no issues. It's also worth noting that the port isn't super secure, so this happens more often than it should. Not really a dealbreaker for me, but it might be for you depending on where you put your dock, so keep that in mind if it's going to be in a place where it might easily fall out. It's definitely an inconvenience.
I have also been reading other reviews that say that this dock doesn't work with their computers. It works well with my computer which is a Dell XPS 15 9560, and the only USB-C port it has is actually a thunderbolt 3 port. Just thought I'd mention that because that might affect compatibility. I don't have any other computers on hand to test it with, so I can only confirm that it works with my model. Look at other reviews if you have a different computer and you're worried about compatibility.

Ethernet problems: need to force update of driver, then no more problems
The Ethernet problems have been resolved after I installed a driver from realtek.com. I received a link to the correct driver from Anker's customer service (they respond fairly quickly). Updating the driver using the Windows "update driver" feature did not achieve anything, you need to download the file from realtek.com. With that issue resolved, I have no more Ethernet connectivity problems. I also experience what some other reviewers commented on, that the hub gets hot, but I don't think that's a problem (the metal casing allows for heat exchange, and while it's hot, it is not too hot to touch). Glad this is a good product, after all!
Earlier review: (was 1 star)
I bought this to make videoconferencing more stable, but the connection fails within one or two minutes, and it is difficult (time-consuming) to re-establish. Every Zoom call is lost, which is particularly bad if you host a call. Wi-Fi was disabled while using this Ethernet hub. I used this with a 2020 HP Spectre x360, running Win 10. I contacted Anker, and they were nice and let me return the hub for a replacement, but the replacement is not any better. Only upside: if you just need a regular connection, for email and web browsing, the Ethernet connection is *very* stable. The problems arise only when video-conferencing.
