read all the bad stories so I thought I would give mine. cheaper unit X50ds, came with the boat, wasnt working right, called customer service on Friday, Feb 11 told me to ship unit to them. sent out UPS Monday Feb 14, recieved unit back with new transducer today. shipping was 4-5 days of total ten days unit was gone. this Lowrace owner is very satisfied with the service I recieved Thumbs Up
