4x 1050 ti using PCI-E 1X 1 TO 4 USB 3.0 EXTENDER RISER?

Hey guys, does anyone here have experience with extender risers?

I saw many youtube videos of people being able to connect 2 gpus using an extender riser and was wondering if it was possible to extend 4 gpu using only 1 motherboard gpu line?

Was thinking of ordering one of these:
and give it a try with 4 1050 ti.

Do you think it’s just a waste of time/money risking this operation?
If this works me and my crypto buddy would try to test out a 32 gpu rig!
