Never heard of a single bad set of Colorado. so not sure why or what PaulIbiker is saying. Come on...as a policy we go above and beyond because I am personally vested in the every product we build in the USA. I design every inch. As the principal I expect my customer service team to follow procedure and policy we put in place. Which if veritably bad is to replace. As a rule, I dont pay attention to this type negative address against the N-fab Brand its futile to debate in most cases. Internet is full of people who need and are looking for attention. But customers who bought N-fab Colorado steps have pointed it out to me. Just Know,,,, If you buy N-fab we are here to take care of our loyal customers. During and after the sale.
