    I’m not sure what happened to my order that I got the incorrect color but the seller corrected the error in record time with zero problems. Great customer service and communication can’t say enough for the seller. But instant communication with lightning fast correction which might’ve been my fault. Good customer service.

    Excellent seller....The item was shipped and packaged very well and arrived as advertised before the expected delivery date. Although....I thought the purchasing price was a little overpriced, it is an OEM new part, so - I can accept the value for the OEM part. Thank you for a great Ebay transaction!
