This was exactly what I was after, a "cheap" dual monitor solution that could provide dual 4K at 60Hz in a (somewhat) single cable solution. I can confirm that it does run hot after long periods (as stated) so interested to see how long it will last. Tip: I was initially getting 24Hz on one of the monitors with the adapter (I am running a 2019 MacBook 16-inch). I found that setting the display to ‘Default for display’ changed it to 60Hz, with the settings staying the same when I went back to my 'Scaled' preference.
