I recently used LOVOON's black PLA filament with my Creality K1 Max. It performed adequately. The diameter consistency was acceptable, and I experienced minimal issues with jamming. Prints came out with a satisfactory surface finish.
While the recommended print speeds are below 150mm/s, it handled slightly higher speeds with some adjustments. Bed adhesion was reliable at 60°C. The filament may need to be dried for best performance.
Overall, it's a functional PLA filament that worked well enough with the K1 Max. If you're looking for a standard black PLA, this is a reasonable option.
