The PLA material seems to be good. Although I hate the way it has been wound in the spool.. every 2 rotations I find that the filament is over-lapped and it looks like it has been wound very unprofessionally. It is so bad that i cannot do long prints as I have to constantly monitor and untangle the filament when it gets stuck. Anybody with a 3D printer will know how bad this is. I have already encountered 2 failed prints because if the filament getting stuck on the spool. Please solve this issue or I will have to move to a different seller.
