I didn't have much joy with the material due to the nature of my printer. It requires a direct drive of the filament to the extruder, and so I am unable to print at its quality. I would say that the staff here were immensely helpful when I queried them for help with the printing, and so rate the service very highly. If you have a DD printer, this filament shows really impressive flexibility, the best I have seen, and so if you are looking for that, it is top marks.
