Query: It doesn't last

This blender has great features and when you first buy it you'll think it's a super product. Unfortunately it doesn't hold up and getting replacement parts is a nightmare. In less than a year I've had to replace the blender container twice because the bearing wears out. This time I've been waiting for over 1 month for the backordered replacement to arrive and the factory says it could still be 4-5 more weeks! What good is the blender when it's grinding it's bearing parts into my smoothie???
