Review on Black PLA Filament, 500g, 1.75mm Diameter by Chad Gravely

I bought this string for $15 thinking it was automatically lower quality string and I was right. However, I did not expect the thread to be so brittle and have such poor tolerances. During the extrusion you could hear the filament creaking, which I've never heard from filament. This was because it was being bent in the extruder, resulting in uneven layers. Really sticky and failed after a 29 hour torture test when it stopped typing after 15 hours due to a clogged nozzle. 10/10 would definitely stay away from it again.
