This bullet blender is one of my best purchases ever. Breakfast is now the fastest, tastiest, and healthiest meal of my day. I make protein shakes, adding skim milk, frozen fruit and nuts. I dump everything in the blender, hit the button, rinse off the blade, add the top and I'm out the door to my law office. Great, on the go, tool for busy professionals. I also make other things like hummus and pesto in this blender. It is a snap and everyone always thinks I'm such a great cook. I just laugh! One word to the wise: If the notches on the cups break off, the blender will not run. The notches lock into position in the blender releasing the safety mechanism and allowing the blender to run. I had a cup that the notches were broken off and I thought this blender was broken, so I ordered a new one. Turns out it was just the cup that need to be replaced. Examine this issue if your blender does not seem to work.
