Reliable and Versatile Adapter for My MacBook Air
I have a 13-inch MacBook Air, M4, 2025, and I use it for everything: work, watching videos and series, and occasionally gaming. I also regularly attend court hearings and professional meetings through Zoom, Google Meet, and similar platforms, so I cannot afford connection issues.
This adapter, especially with its LAN port, has been very useful. It gives me more confidence when attending hearings online because I can rely on a stable wired connection. It also works well while connecting other devices, such as microphones or pen drives, which makes it very versatile.
The finish and materials feel solid and high-quality. I used to have a white plastic adapter from another brand, but it ended up changing color with use. This one stays cleaner, looks more professional, and is easier to keep in good condition.
It is easy to carry, practical, and very efficient.

Good quality product
Good value for the price I paid. I have all the slots in use and it works fine. It really helps increase the reading and network speeds, if (like in my case) I have to use both ethernet and/or wifi antenna for my company laptop.
It is slim, sturdy, discreet and I like the main cable that connects to the PC is very flexible like a cord.
Very happy with it.
The only downside is that it gets very hot, I don't know why, but other than this, it really meets my expectations!

One cable does it all, rock solid Ethernet and great 4K output
This hub has simplified my desk setup considerably. I plug it into my MacBook and instantly have Ethernet, 4K HDMI, two USB-A ports, and 100W charging all from one connection. The Ethernet is Gigabit and the speeds are as fast as plugging directly into the router. The 4K HDMI output to my monitor is clean with no flickering. It runs slightly warm during extended use but nothing alarming. Build quality feels solid and UGREEN has been consistently reliable in my experience. Worth every penny if you need to expand a USB-C only laptop.
