Ohh, I'm envious! Lucky you. I have the magic bullet, love it!!! I've been hinting that I want a nutri-bullet but no luck so far. Once my magic bullet bites the dust, I'm most definitely buying myself one!
Not only smoothies, I have used it to purée soups and sauces, easier to clean than my big blender and sometimes the immersion blender just doesn't make it silky smooth, ya know?
I agree that it has been helping me to be able to get in more fruits and veggies especially with the easy clean up too so in turn, it helps me stay on track and lose.
