Review on USB C Hub Dual 4K HDMI Triple Display Adapter for MacBook Air/Pro 2020-2017 | 7-in-2 🔌 Silver Dongle | 100W USB-C Hub | SD & Micro SD Reader | USB 3 & USB 2 by Brendan Baker

I bought this hub primarily because I wanted Gigabit Ethernet to be able to transfer very large files faster every now and then. I have several other hubs and adapters for USB-A ports, SD card readers, and HDMI (thanks Apple for removing all of that!), but it's nice to have it all in one device. I like the 2-port USB-C car mount as the hub doesn't wobble like many others at the end of a short cable. One issue I had when installing the hub was that the bottom was protruding significantly below the bottom of the MacBook Air case. I was afraid the MacBook might rock back and forth on a flat surface. However, after putting it on the table, I found that this wasn't a problem. It's actually the curvature of the MacBook's underside that makes the hub appear to protrude too far down; But that's not the case. It lies perfectly flat on the table. I ran some basic performance tests on this hub and am happy with the results. My tests aren't as comprehensive as a review site, I just use what I have on hand. * Gigabit Ethernet: I used the free software "iperf3" to test the connection speed between M1 MacBook Air and 2015 iMac on the same network. Switch. The best result is 938 Mbps. Pretty close to gigabit and I didn't expect more in real life situations.* SD card reader: I tested a 128GB SanDisk Extreme PRO SDXC UHS-I card and got 87.6MB/s. The product page for the SD card says it has read speeds of up to 170MB/s, but my 87.6MB/s matches tests I found online.* MicroSD card reader: Tested with SanDisk 256GB Ultra microSDXC UHS-I memory card and achieved 88.7 MB/s. * USB Connections: I used the same SanDisk SDXC card as above, along with a Transcend TS-RDF5K USB 3.1 card reader and a Nonda USB-C to USB adapter. It's far from ideal as each of the above can limit speeds well below USB speeds, but hey, that's what I had available. Here are the results: * Transcend memory card reader + Nonda adapter connected to MacBook USB-C port (without Nov8Tech): 85.3 MB/s* Transcend memory card reader connected to Nov8Tech USB-A port: 85.2 MB/s (same for both ports)* Transcend card reader + Nonda adapter connected to rear USB-C port Nov8Tech: 85.4 MB/s* Transcend card reader + Nonda adapter connected to front USB-C port Port Nov8Tech panels: 34.9 MB/s. front USB-C port on Nov8Tech hub, less than half the speed of all other ports. I got the same result several times. So the rear USB-C port is faster, but it's also the only one of the two that provides pass-through power for the MacBook. It's a pity, but it's a small problem. A short shutdown time for the best USB-C speeds isn't bad given the MacBook's excellent battery life. I checked the HDMI port, no problem connecting to my Samsung 4K TV. I don't have Thunderbolt devices, so I couldn't test the Thunderbolt connection to the rear USB-C port.
