Query: Minute mixer

My wife took the brand new Oster 6 speed hand blender out of the box, started to whip some cream into whipping cream (yes, some people do still make their own whipping cream), and before the cream was suppose to turn into the whipped form, the motor burned out. This product has been the worst performing item I have ever seen; I'm going to refund this puppy.
