you generally get what you pay for where filament is concerned, it's also very dependant on your printer, extruder and hotend, i wouldn't even bother trying to run this stuff on an up! or a stock standard mk7 extruder, but it should go fine 1.75mm and somthing with a jhead or one of my hotends (aluhotend) on it, the concern used to be diameter consistancy with chinese filament, however these days the bigger concern is more about foreign dirt inside the plastic itself especially as we are now looking at 0.3mm 0.2mm and 0.1mm nozzles as becomming a standard thing in the very near future
