It’s the same one that’s on the Mosaic printers, but not the same one in the extruder kits they sell separately.
So far my QU-BD experience has not been positive. I shipped my original pair back for replacement with tested known-good units and I’m still not having any luck. At this point I think it’s not getting hot enough (either the thermistor is calibrated wrong or the heat isn’t making it into the melt zone) and previously it would extrude a few mm and then jam.
My Makergear extruder was relentless so I’m confident that with a better hot-end arrangement it will do the trick, I just made the mistake of thinking I could just replace it with the QU-BD and “plug in and print”, now I know better 
@Jason_Gullickson , you having positive experiences with Makergear hot ends, you would absolutely be shocked at the performance of a Budaschnozzle or J-head.
@Jason_Gullickson I’ve been using my MakerGear extruder since May (pretty heavily) without an issues. Every now and then I get some filament that strips a little, but that’s been fairly rare, and I do blame the mish-mash of filament I use.
