Works as advertised
Did the job for me, making a more compact set up with a device that has a microHDMI port. Looks as if it doesn't fit on a Pi 4 *if* you want to use *both* HDMI outputs. Needs to be more compact. The workaround may be to use *one* of these devices and one short microHDMI(M) to HDMI(F) adapter cable on the other microHDMI port. The description of this product should probably reflect this restriction.
