Review on Satechi Aluminum Type-C Clamp Hub Pro with USB-C Data Port, USB-A 3.0 Data, Micro/SD Card Reader - Compatible with 2019/2017 iMac & iMac Pro, Excludes 2021 iMac (Space Gray) by Darrell Shreves

High quality product. Ease of installation. Works well with some known issues. problems1. The force to insert and remove one of the plugs is so great that you need 2 hands. One to hold the screen so it doesn't move and one to insert or remove the device connector or SIM card.2. The USB ports are not occupied power ports (like the USB ports in the iMAC. My external Apple DVD Super Drive cannot be used in these USB ports of the junction box because the iMAC is blinking. You need a powered port to use the external Apple DVD drive. Overall I like the product as I hated having to reach for the 2017 iMAC screen to insert Sims and/or USB cables. I've only had the product for a few days and I will post any problems that may arise in the future.
