The concept of a personal size cup is great. The blades are not powerful enough to handle the type of fruit and vegetable smoothies I prepare easily with the VitaMix. This personal cup I feel is best for anyone preparing smooth smoothies and not needing to breakdown vegetables like beets. The personal cup let my smoothie very gritty. I plan to return the item after 3 uses as I am unhappy with this item. I love my full size vitamix for the daily smoothies I prepare for myself.
