    The product's condition and quality was as advertised, which matched its reasonable pricing. The digital temperature control display and lighting looked great. Unfortunately, it did not fit the new aftermarket Head Unit. The Seller responded promptly to my request for a refund and once they were in receipt of returned item, they immediately provided my refund. This Seller provided excellent customer service and runs an ethical business.
