This personal Nutri Bullet gives a big burst of power! I have been making smoothies every morning. I have been using both fresh and frozen berries and veggies. The blades chop and pulse both the fresh and frozen items with ease. It was easy to assemble and use right out of the box. There are some great recipes that come with this purchase. One of my favorite smoothies I have been making is a berry smoothie. 1/2 cup of frozen blueberries, 1/4 cup of cashew milk, 1 cup of spinach, and 1 large banana. The shaker bottle accessories I use daily to take my smoothie on the go.
