My Ninja Foodi Power Nutri Duo Smoothie Bowl Maker and Personal Belnder is amazing!  I just throw in my ingredients and blend.  It is so powerful I never have to worry about have large unblended chunks.  It makes the smoothest smoothie! I generally put ice, Greek yogurt, frozen fruit, milk, sometimes add greens and/or peanut butter and it's perfect EVERYTIME.  Simply the best and easy to clean up. I'm now a daily user, I love it so much.
