Query: Death By Margarita

The price is great and the glass jar is great. The problem is that this blender just does not hold up if you are blending frozen drinks, such as Margaritas and Ice-Blended Mochas. After a year of blending an average of two of these drinks a week (just on weekends and one per person, mind you) the motor is burning out and the acrid smell of burned metal and plastic fills the air.
