I've used them.
I bought 5kgs of PLA 1.7mm
Black, Natural, Red, Blue and Purple.
I have used them all except Purple and I like it so far. I just made a big order of 33kg with a group of friends. Lets hope its just as good
The settings differed for different colors as always. The temps ranged from 195-210. The diameters were pretty decent but you need to measure it to get an average.
