Throw this item in the mix. Blend??? Destroy! Except for maybe rocks this thing will crush anything, pulverize, reduce it to it’s molecular level, it puts the word smooth in smoothie. Big batch or single serve with the versatile single serving cups no job is too big or too small. Super lid keeps your blueberries off the ceiling, easy to clean too. Careful with the blade, it’s like some kind of Ninja (the Japanese kind) throwing weapon, and it’s sharp. Durable, heavy duty construction, ours has been in daily service for over a year and no issues. Suction cup feet keep it firmly in place. Downside is it’s loud (What?) but find me a blender that isn’t. Buy it here:
