I don't know how I ever lived without it.
I'm very happy with this device. My laptop doesn't have an ethernet port and only has one USB-C SuperSpeed port, so I bought an ethernet to USB-C cable to connect my ethernet switch to the Anker and into my laptop's USB-C port, and it works great. I don't need a fast internet connection for the things I do, so my service is only a 50mbps symmetrical up/down connection, and that's what I get even while transferring files from my external between other devices, charging my phone, and using composite devices.
I bought the Anker 100W Compact and Foldable USB C Charger for it and it charges my S24 extremely fast.
It's very well built, yet super lightweight. I love the sleek, slender design. It's the perfect size to easily slide into a pocket, store in a desk drawer, or keep handy in a laptop case or backpack.
Using it is easy. Just plug it into your computer and plug your devices into it. Just make sure you have a power supply for it if you're charging or powering other devices, using external storage, or running anything else that taxes USB power.
I have had ZERO connectivity issues with it — no random disconnect/reconnect blips, no failed transfers for huge amounts of data that have taken up to 45 minutes, no static his or crackle when my headset is running through it... no problems at all. It's actually kind of spooky now that I think about it... I can't recall a time I've ever had a similar device that didn't have some nuance that got under my skin, like a loose connection, random disconnections, having to reinstall the drivers all the time, or having to troubleshoot just to get it connected for the first time.
The most stress I've put it through was with my keyboard connected, ethernet running through it, my S24 charging and transferring about ~20gb of pictures and videos to my 2T external HD at the same time that my laptop was transferring about ~500gb of media and documents to the HD, too, and I was surprised by how warm it DIDN'T get.
My only complaint is trivial and unique to my situation — I wish output cord was longer. About six inches would do. My laptop sits up on an adjustable stand that clamps to my desk, and the end where the output cord is hangs a few inches off of my desk. This puts extra stress on the USB-C port and can wear it out faster or damage it.
I haven't had a use for the HDMI port yet, but I eventually will. I use all of the other ports for my work and personal devices, though. These include: a 2tb external hard drive; a Poly Blackwire 3320 Series headset; a dongle for a wireless mouse/keyboard combo or a wired keyboard and a dongle for a wireless mouse; my Galaxy S24 charges and transfers files through it super fast; I have several thumb drives ranging from 20gb to 512gb that I regularly use; I recently bought an RCA/S Video-to-USB converter to digitize old home movies I plug into it, too.

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.
