Took a much longer time to receive the Knobs. Wrong knobs was sent to me, trying to get in contact with customer service for a replacement is a nightmare. It took them so long and asking the same questions over and over again to place a replacement. After 3 weeks, no replacement order was initiated. I was forced to cancel the entire order for a full refund. Another nightmare just began... just sent the 3rd request to acknowledged the refund, but no answers. DO NOT BUY FROM THIS COMPANY! PERIOD!
