I was surprised when I opened this and found the filament to behave like a wet noodle! Despite this, it has mostly worked in my unmodified Ender 3, although I've had a few jams that I blame on software slicing errors and bad bed leveling. Improving the contraining of the Ender3 extrusion path might make this better.
Printed parts with this plastic have intersting properties very different from other non-tpu plastics.
I've been keeping this in a ziplock bag with silica dessicant when not in use to preserve its shelf life.
