Review on ESUN 3Mm Cool White PLA PRO (PLA ) 3D Printer Filament 1KG Spool (2 by Trevor Rodke

This filament used to get 5 stars easily, but the last two spools I used were terrible. Every few prints and overnight, breaks form in the filament from the spool to the printhead (Lulzbot Taz 6). At best it is problematic to remove the bad part with a loss of about 3-5 feet, but I also had a crack in the center of the footprints which causes the footprint to fail if not caught in time ( there is approximately a 5 minute window on the Taz 6) or a defect caused by its replacement. Bad spots are extremely brittle and are more likely to break than bend. When I first encountered this I thought it was a one off issue but the next reel bought about a month later had the same issue. Both were brand new, vacuum sealed and used immediately after opening. I've been using this brand for several years with no problems so it looks like something is wrong with the factory. Maybe I'll give them time to fix the problem and come back later. UPDATE 11/16/20: As mentioned above, I took a break from this thread but recently had to revisit it as my current favorite was missing. stocks and I can report that it is worse than ever. In fact, I'm writing this review while taking a break from disassembling one of my printers to clear debris clogging the feed hose.
