Karen C Green Valley , AZ September 15, 2015 Our glender drive coupler disintegrated We purchased a new coupler from Appliance Parts. We make smoothies every day, so we were desperate! But Appliance Parts got the part to us in two days, and the instructions that came with it were easy to follow. Our blender works perfectly again!
