Review on 💻 Satechi Type-C Dual Multimedia Adapter - Dual 4K HDMI, USB-C PD, Gigabit Ethernet, Micro/SD Card Readers, USB 3.0 - Compatible with 2020 MacBook Pro, 2020 MacBook Air, 2020 Mac Mini (Space Gray) by Dave Butler

The idea is great - instead of having multiple keys hanging off your laptop, you can do everything with just one key. It's a pity that the HDMI output is very unreliable, to say the least. When I connected two external monitors for the first time, only one of them got a signal. After a few changes to the connection, I got a signal on both monitors. However, the connection isn't very good, and if I move the laptop even slightly, the connection drops again and one or both monitors lose signal. Even if I don't move the laptop but put it to sleep and wake it up the next day, I sometimes lose the signal to one of the monitors. It's just not worth fiddling with it multiple times a day to get it working as usual.
