Since I got this for my husband for Christmas this year, we have used it everyday! Most recipes call for blending the spinach/kale first with the liquids, but you really don't have to with this machine. We toss in the greens, almond milk and whatever else we want to add (pineapple usually). I literally gag if there are big pieces of spinach in my shakes, but it's never happened with the ninja. Love it!
