In last week's poll I asked what matters most when buying filament, and the number one response by a large margin was "Quality - the most reliable performance". This pleasantly surprised me, as an assumption of mine had been that cost would win out.

Refocusing on quality, though, it begs a follow-up. What is quality? I qualified the response last week with "the most reliable performance" but that in and of itself is a pretty broad cover for different facets of "quality". So tell me, what most makes a filament "quality" to you?
