Good hub if you're missing an ethernet port and want one
Bought this for my laptop that lacks an ethernet port. The connectivity is perfect. Have had it now for over 6 months and no issues; not surprised as it is an Anker (always reliable for me). Nice to have an extra USB-C port, as well as 2 USB-A's. Haven't used the display port, so can't comment on that. Nice and compact.

Good Transitional Product
This item worked perfectly when I upgraded my computer and needed both USB and Thunderbolt ports. Great item!

Reliable and power hub
I use most of the ports on this hub and other slightly cheaper hubs caused my monitors to turn off and back on frequently, presumably a power issue.
As long as I have my computer charger plugged into the hub this has not been an issue with the anker one.

Works great but gets warm.
Overall, this is a pretty good product with a few minor flaws.
First, every port seems to work great. I purchased this so I could use the dual display feature on my iPad Pro and cast onto an external monitor through the HDMI port. Works like a charm. The USB ports work great as well, and the USB C has proven surprisingly functional. The power through charging (plugging in a regular power cord to the hub to charge the iPad) has had some issues, but I believe it was mainly because I was using the regular iPad charger that came with my iPad, and it wasn’t powerful enough for the charging through the hub. It was a 20 watt charger and I need 30 watts. I have yet to get a 30 watt but I am sure that will fix my problem.
The other flaw I have noticed is that it tends to warm up rather quickly. From my personal experience, this seems to be fairly common with these USB C hubs. This one in particular gets warm quickly, like within 20 minutes or so after using the HDMI and at least 1 USB port, which is rather fast compared to other hubs. That being said, it hasn’t gotten really HOT, just warm. Even after couple hour study session, it is still just warm, so that is good.
Anyways like I stated, this is a pretty good hub and for the price is probably hard to beat. I would recommend this to someone who is looking to increase their productivity of a device that has USB C.

Complete essential for anyone with a MacBook Air
If you're a MacBook Air / laptop with only USB-C ports, this is a total essential. It's an all in one hub to connect to all your devices
You can hook up to monitors, plug in dongles for your mouse, etc that you wouldn't be able to. I'm able to display at 2K with this to extend my laptop and use a mouse with a USB-A dongle thanks to it. It's sleek, well designed, slim, and has a stylish LED indicator.
And if you have a monitor that supports power delivery you don't even need to use your charging cable and can charge straight out of this.
I really can't think of any cons.
