Review on YOYI 3D Printer Filament - PETG 1.75Mm 2.2Lbs(1Kg) Spool, High Accuracy +/- 0.03 Mm, 100% New Raw Material! by Ricardo Stewart

I purchased this filament despite the other negative feedback and this filament turned out to work just fine.Printed perfectly out of the bag with basically no modification from my PLA print settings (only bumped the extruder temp up to 235).PETG is fairly hydroscopic so it will absorb moisture out of the air over the course of a few days. I ended up getting 3-4 days worth of printing out of this roll before I had to dry it.Please note: I attempted to dry this filament at 180F in the oven for 4 hours and now have a solid doughnut of very nice looking PETG. I would suggest using a lower temperature (140-150F?) for longer (6 hours?) to prevent this type of bonding. This however was totally my fault and the fault of this filament. I should have experimented a bit, but was in a rush, now I gotta order more.
