The slave issue is attept to get around a poor hydrolic system in the Z. Rob does not make the slaves, But gives them away with the Max clutches.....For a period of time the only thing available in the right size was an aluminum slave.....During that time about 75 to 100 clutches were sold and aluminum slaves were given out....All of the aluminum slaves failed and Rob gave new ones with free shipping to everyone. He did not raise the price on the clutches to give the slaves away, and when the product he bought and gave away went bad he bought a better product and gave them away again. I do not Know any other Co. that stands behind their products like RPS.
RPS is not afriad of failures either, Failures means your trying new things and trying to be the best! No matter how much you bench test something the real world will turn up other issues. Even something with as big as the space suttle has failures. With RPS failures result in better products every time.
