Review on 4K HDMI, 2 USB 3.0 Port, SD/TF Thunderbolt 3 USB C Hub Adapters For MacBook Pro 2020-2018 by Andrew Carrao

This device fits my new Macbook Air M1 perfectly. Memory card transfer is awesome. Mouse and Keyboard work great.Some issues I have had in a week of use:- If the Macbook lid is closed, this USB C adaptor device keeps it's indicator light on, consuming battery. It probably prevents the Macbook from going to sleep. I have left it there to test and it never turns off. This happens with or without HDMI external monitor connected.- When connecting hdmi it takes sometimes up to half a minute to start sending signal to the monitor. Same issue if the monitor is already connected to hdmi but the monitor itself starts sleep or is turned on. off.- A couple of times, the laptop went to sleep on a lunch break, and the external monitor never received hdmi signal back again. I had to unplug, then plug again the USB C adapter for it to start sending video via hdmi.Other than that, it is perfect.
