I recieved this product for free, for my honest review.
This morning I made smoothies for my daughter and myself for breakfast. First I made my daughters. Hers was made with frozen diced fruit and milk. Strawberries, peaches and bananas. At first, it wouldn't end at all. I had to keep stopping it, opening the lid and mix the stuff around. Finally it blended up. 
My smoothie consisted of frozen berries and a banana, and milk. While it was blending, I had to shake it around a bit and then it finally blended. 
For future smoothies, I'll just stick to using my little ninja blender. [This review was collected as part of a promotion.]
