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

The stuff is great, absolutely beautiful. However it is PETG and it is stringy and took me a long while to tweak a lot of settings to get this thing to print right. I had the most success printing at speeds of 30mm/s and at 240C. It is strong, great layer adhesion and looks great, just be warned if you never printed with PETG before, it takes patience to get it right. (manufacturer recommends 250-275C printed up to 60mm/s) I don't recommend those speeds, itll just make a mess and will fail your prints. my printer had a hard time with temps up to 275 (anet a8 with e3d allmetal hotend) but when I did, I always got clogs.I did not have an issue with tangled spool, or wet/dirty filament and they should give themselves better credit for the thickness tolerance of the filament. Prints as PETG should, hot and slow. they are optimistic recommending 60mm/s for a print.
