Review on Towond MacBook Air USB Adapter: 3-in-1 Thunderbolt 3 Hub for MacBook Pro 2019/2018/2017, MacBook Air 2019/2018, 4K HDMI, 100W PD, 40Gbps 5K@60Hz, USB 3.0 - Buy Now! by Justin Gerrero

I really like the aluminum body of this hub. Doesn't look like cheap plastic. The color is very similar to the space gray Macbook Pro. What I like best is that this hub fits in a laptop bag! The downsides are that it doesn't have many ports. Perhaps an additional USB-C port or a TB3 port would be ideal for this. I noticed that the USB-C port can drive a monitor BUT it only supports up to 4k 30hz. I was hoping that my USB-C -> Display Port would be perfect for this, but unfortunately it's not. In addition to a second monitor with HDMI. I had two monitors (4k and 1080p, both running at 60Hz on one hub). Unfortunately, for some reason, the hub doesn't work at all when plugged into the right side. The DP -> to USB-C port is also very finicky and seems to refuse to boot every now and then. I was having trouble getting my 4k monitor to display my screen. In the end it worked again. I would like it to be much more reliable.
