They use old regrind when they manufacture their parts. Regrind gets stored in old dirty boxes that sit on the bare floor. They use regrind on critical parts that call for 100% virgin material. I have seen black regrind so old it had a brown tint to it. It was causing the plastic to come out of the barrel with bubbles in it. It was causing the parts to be defective. Company also has serious integrity and honesty issues.
