Today while making a simple drink, (milk, chocolate powder and a banana) my magic bullet started smoking. White smoke just started billowing out of it, the smell has run us out of the house. There was nothing hard to blend, plenty of liquid in the cup, and was only blending for 20 seconds tops. It has been two hours, the smell coming from the blender that is 5 feet away as I type is unbelievable. Has there been a problem with these catching on fire?
