I had purchased a few 1kg spools (white,black, and gray) and they work great with my Monoprice Maker Select. I've had alot of issues with the .5kg brown not feeding properly. Problem #1 filament too thin for some layers & Problem #2 filament stops printing.
I've found that I can push the filament while heated to get it working again. Therefore, it appears the tolerances are not very good.
I'm unsure if this is due to color or spool size, but not happy with this one.
