This is by far the best PETG ESD I have used and is very competitively priced!I would really like to see 1kg spool though, 0.5kg spools are really annoying to work with since I'm constantly having to swap to a new spool mid print. And, with the switch to the Fiberon branding, they started taping the end of the filament to the spool core. This is a big PROBLEM as it can get stuck during when the filament runs out cause the filament runout sensor not to trigger. PLEASE revert back to not using tape.Also, I'd really like to see Polymaker submit well tuned filament profiles for all the Prusa machines to Prusa Slicer.
