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

The quality of the plastic was good. Went through ten rolls in 5 days on four different printers with no jams. Tolerances seems to be solid. Only complaint is the packaging. Nothing was vacuum sealed. The rolls would fall out of the plastic bag and hit the floor when I picked up the bag. Would not buy this brand if I was to store the rolls for any length of time because of the packaging. Also, please don't send you customers your waste filament and say it's a gift. Every roll had about 2 grams of clear filament as a "gift". Most of this filament was dries up and would snap when slightly bent.
