Query: Excellent customer service

Wrong product was shipped at first, OK anyone can make a mistake. But then I was overnighted the correct product without asking, and then given a preformed shipping label to return the incorrect product for free S&H.;Couldn't ask for a better company to do business with in the future.Gates belt was exactly as what you'd expect from a new quality belt.
