Query: love the smell of burning motor in the morning

I was excited about this blender, seemed well designed and powerful enough for everyday needs. The first time I used it, I could smell the motor burning after about 5 seconds. The second time I used it, it shorted out attempting to blend some frozen fruit with yogurt and plenty of liquid. So surprised that Cuisenart made something of such poor quality. That was the last time I used it ;)
