I bought 4 of these spools, and as best as I can tell, the filament is trash. It's done nothing but clog and not print properly on my genuine E3D V6 hotend and the same on the genuine E3D lite6. I have had no issues extruding other filaments with very little tweaks, but this stuff from Deltraprintr took 3 days before it shipped, arrived with very tiny packets of the silica stuff and seems to have junk in the filament. Keeps clogging all of my extruders, even when I try run it at 260C on the E3D V6 hotends. Nothing I've tried to print ever completed, and after running the stuff, I had to do a cold pull to clean the hotend path. I did manage to print a red marvin with the E3D V6 and a E3D titan extruder, but even that came out inconsistent.
Short story, it's cheap and on sale because its junk and I got what I paid for, which was cheap and crappy filament. Lesson learned, won't be ordering again.
