Review on High-Quality Melca Black PLA 3D Printer Filament, 1Kg Spool, 1.75Mm Diameter With Precise Tolerance by Cary Clemons

Ordered this filament a while back and am now getting around to printing with it. Unfortunately, with only about 1/5 of the roll used, I've now had two jams caused by out-of-round/oblong filament. In the one case I measured, it was 1.60mm on one axis and 1.97 on the perpendicular. Too bad too, it looked like it was extruding pretty well.I pulled off and discarded a few meters in each case, but not enough I guess as the two jams were pretty close together. Hopefully I'm now past the bad patch.Edit: +1 star for customer service. I was offered a replacement spool from an upcoming, improved batch. I'll revisit this review once that spool is received and I've printed a bit with it.
