Bests & Worsts Reviews from Amazon

I'll let my photo do the talking. Cylinder on the left was printed before using this cleaning filament. The one in the right was printed after. I ran approximately 8cm of it through my head. There weren't any instructions so I extruded 4cm at 250c and 4cm at 190c. The results speak for themselves. Round surfaces were getting a rough texture, now they are smooth. Good stuff.
