    This involved my first purchase at CompSource. First, the shipping was much quicker than expected. There was a problem with the product (a well-known manufacturer), although no fault of CompSource. Compsource customer service and communication were very good. They handled everything in a professional manner. Bottom line, I am very satisfied with CompSources service, and plan to order from them again.
