$9.50 per spool. Good price for Sunlu... Although pretty "standard" price... Would like to see $8 per spool for Slickdeals.

I'll just mention I recently bought a package of spools from Sunlu. 1 of them won't feed in my printer - the filament seems to be slightly undersized. Sunlu had no interest in replacing it or refunding me for the problem - I had to dispute it with my CC company.

Any modern bed slinger can print at high speeds.

"High speed" filaments, whether PETG, PLA, or something else, are designed to melt, flow, and cool "better" than regular filaments at higher speeds that demand these qualities. They'll work just fine at slower speeds. Kinda like hi-test gas works fine in your (& my) economy car. It's only when your sports-car printer is pushing the limits that its benefits might become apparent.

I think their filament is good but their colors are so weak. Elegoo PETG is far more opaque.
You'll see a lot more bleed & color obscurity, in comparison.

Yeah that sales email for customer service goes pretty silent when you mention the word return.

what makes filament high speed, better bonding at high print speed? Does it mean i should only stick with slow or regular speed filament for an old 50mm/s printer?
