Never used a filament that was this horrible in my life of 3d printing. I tried printing this filament at 220 to 250c and no matter what temp i use the prints hardly ever stick and when they do stick they print for a small amount of time before cloging ur nozel every single time. And for what it does manage to get printed tends to crumble or fall apart, i have tried every thing like layer hight and print speed and even a size 0.6 nozel as well to no avil. Even if it was just just a sticking problem id deal with it but Everything i try to print clogs the nozel and if u get it to print the prints fall apart. this filament is complete garbage. Ill never get this brand again.
