Cindy G Champaign , IL June 28, 2014 Blender coupler completely disintegrated Removing the base of the coupler from the blender was difficult since all the black blade part was gone. This did take awhile but your video was very helpful. After I received the part it just took seconds to screw it on the base of the blender. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
