The Bosch blender is great for making smoothies but just remember that frozen fruit is very fibrous. First, turn your blender on before adding the fruit. The Bosch motor is so strong that it makes the blender blades jump into action. If you have filled the blender with fruit or other ingredients, it is just like is like us trying to run in water. Another footnote: Chop the strawberries and bananas before blending as they are a thicker fruit. Have fun blending with your Bosch blender today.
