Review on ✨ Enhanced Efficiency: MOSDART USB-C to 4 Ports USB 3.0 Hub Adapter for MacBook Pro, iMac, Chromebook, Pixelbook, XPS, Samsung S9 and More by Matthew Kocur

Pretty to look at, if a little big for a 4-port USB-A -> USB-C docking station. Looks solid and works right out of the box. After about 3-4 minutes of work, when I isolated the problem, it's causing a lot of Bluetooth interference on MacBook Pro 15 and 16. Using Bluetooth Explorer, I observed the relays and the signal quality. I unplugged each item individually from my laptop (4 USB-C ports were in use) and as soon as I removed this unit I saw an immediate 90 percent reduction in retransmissions and a MUCH better signal. I repeated just to be sure. Same results. If you are using Bluetooth, do not use this device. I also suspect it interferes with 2.4GHz WiFi (much more power than Bluetooth, so maybe not as much), but this hasn't been tested and is just a guess.
