Great way to connect my Ethernet to my MacBook Pro....
Size: USB C to Ethernet Adapter
Needed to direct connect to my Modem / Router, but my MacBook Pro, being more modern, and slimmer, doesn't have an Ethernet port anymore (thank goodness). This worked perfectly; just plugged it in and ripped...definitely Plug-n-Play for my Mac. Quality is good (what else do you expect from Anker).

Easy to use Plug and Play
Size: USB C to Ethernet Adapter
The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.
Size: USB C to Ethernet Adapter
For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer. I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.
