Query: Shockingly poor quality

The blender jar does not fit tightly on the base, it wobbles around loosely and makes grinding noises if too far off center. The motor has a strong burnt rubber smell. After 6 calls to waring customer service I finally got a hold of someone who explained that the blender is not defective. Both of these issues are normal. I really wish the engineers had done a better job. I love the look of the blender and would have been happy to support an American manufacturer in an industry dominated by Asian imports.
