I’ve had a few spools. I’ve found inland from micro center to be really good filament. I haven’t noticed much difference between the two. Also, there are some top tier filament manufacturers in the US. Pricey stuff but no more than prusa and shipping is free to low.
Stuff sticks to my pei sheet TOO well. Clean it well… Soap and water with a new clean soft sponge. Get all the glue off and any other gunk and oil. Wipe it dry with a clean towel. Lightly rub it down with isopropyl alcohol. When dry, print on it with nothing on the sheet. I can go like 20 big prints before I have to clean it again.
