Geeetech 2in 1out hot end extruder

Has anyone used the geetech friends 2in 1 out hot end extruder yet? I searched but didn’t see any threads for this.

Its a knock off of the E3DV6 Chimera Bowden setup. Works about the same. Basically your main issue with that type of setup is attempting to print with only fillament in one of the extruders. In that scenario fillament feeds back up into the empty barrel, burns up and carbonizes. Aside from that it’s basically a bowden setup with a thingy.

Thanks piercet. I found more for the 2-in 1-out using the Filastruder Cyclops hotend & Bond Tech Extruder below. I believe that to be a complete solution once I get all of the materials and software outlined.
