Review on Titanium Thermal Feeding Heatbreak Extruder by Mark Ponnusamy

I am new to 3D printing but not to making beautiful metal parts. They are true to size, perfectly finished inside and out and definitely made of real titanium. They don't joke about how well polished they are on the inside. My only criticism and not enough to even deduct a star is that I would like them to break the edge of the threads a bit. They are sharper than I would leave them, but still fully usable. Just use a piece of leather or something between the threads and your fingers when tightening. It has an M6 thread on the cooler side and an M5 thread on the nozzle side and works great with my other V6 bits. I have no idea what else it might or might not work with.
