Very smooth printing filament straight out of the box. Love Ziro filament. Transition was rapid, more than I prefer, but it was clear in the description. Performed perfectly straight out of the package. Beautiful colors. But, that being said, the colors were MUCH brighter than image shown. I made many beautiful items. Just not the ones I purchased the filament to make. Quality was great. Color was not what I expected from the images. Beautiful, but still, I wanted muted colors and received vivid colors.
