Query: Terrible

I've been using this blender for about six weeks to make a daily breakfast smoothie that involves yogurt, frozen blueberries, and a banana. Nothing extreme. The plastic base cracked within two weeks. The blade assembly has rust sprouting everywhere. It is extremely LOUD (worse now that the base is cracked) and unpleasant. The glass carafe seems well made but the rest of it is just junk.
