This was purchased from a used car dealer because I thought we had an issue with our brakes on a 2014 Nissan Leaf.  It turned out that we had no issue so we are selling it.  We bought it with the assurance that it worked and was out of a wrecked Leaf that was hit from the back.  This was a reputable dealer on ebay so we had no reason to assume otherwise.  We know how to pack and only actual shipping charges will be charged.  We will refund if the actual shipping is less than the ebay listed shipping cost.  The unit weighs 27 pounds packed.
