Question: If you have tried a dodgy dual input hotend, what were your experiences?

Background: As with anyone else who have a single extruder, I’ve been contemplating upgrading to something with a bit more flexibility. But the idea of getting a whole new printer doesn’t appeal as much to my wallet, as it does to my mind :-)

Scouring aliexpress for weird filaments with the mrs - you know, normal Saturday-evening-and-the-kids-are-sleeping couple activities - we fell upon a dual input hotend for creality cr10. It looks an awful lot like the hotend we have, and it comes with either 24v or 12v heater. It’s only about 15€ so I might just give it a try, but it’s pretty stupid when I don’t even have a plan for an extra extruder as well. And I don’t know how I would go about wiring that part up on my cr6 at the moment.
