This appears to be very well machined. I printed some flexible material with it and it printed perfect. With my stock nozzle same settings print failed.
Have not had any clogs. They are great
I've been using this nozzle for about 2 months now, pretty much printing 24/7 and I haven't noticed any change with the nozzle or print quality. This thing has had every type of PLA through it, normal, glow in the dark, metal embedded, carbon fiber. Takes it all like a champ.
Order was fast and the filament great, got the CF HTPLA and enjoy printing with it.
Initially good results .
