Today I installed one of the Spirit's belt-driven variants, but saw no advantage on the UM2 extrusion test, and had some issues with changing filament, so I went back to |Robert|s feeder: the convenience for doing a cold-pull atomic method, and not having to fool around with the UM2 Change Filament routine makes it a superior alternative for me.
However, I've got my hopes up for a UM2 Flex3Drive mod...

For what it's worth, I tried most of the feeders out there. And had problems with them all. No offense to you guys and your hard work, I really appreciate the effort! I've been using this one for the past 2000 print hours or more with absolutely no issues. Printing in Ninja Flex, Nylon ABS and PLA.

Keep in mind that I'm more volume/production oriented, so I pound this feeder 24/7. So far, the only sign of wear is at the filament entrance where the filament rubs the opening orifice. Shouldn't have to print another one for another 2000 hours or so, if that.
Update:
Takei Naodar has sent me this feeder with filament change capabilities. We'll see how that goes. Keep ya posted.
