I have been making smoothies out of ice, milk, frozen bananas, and peanut butter for my kids for many years. I was excited to try this magic bullet with the expectation the kids could take over their own smoothie making with this magic bullet that is appropriately-sized for a single smoothie. Unfortunately, it failed to crush the ice to make a smooth smoothie. There were large chunks of ice remaining when I tried It with just ice, and the same result when I tried it with milk and the ice. In the end, I could not get the ice pulverized, and gave up. That being said, the magic bullet seems to be well-made. It is compact too. I also liked the varying cup sizes that came with it.
