Review on Sindoh Filament Compatible Millimeters Diameter Additive Manufacturing Products in 3D Printing Supplies by John Rocha

I bought 2 spools of this stuff and both have problems. The thread has wound itself on itself and stops flowing and breaks. This happened repeatedly. I discussed this with a company representative at an international trade show who said the coils would be replaced. It was 4 months ago. They sent me form after form and asked me to fill them all out and send them back. I wrote several letters, but again no replies. Perhaps this review will catch your attention. If so then I will update it.
