I've only started using my NutriBulletRx this week with a few recommended recipes from the enclosed book, which directs all the recipes (with the exception of the Soup recipes), to use the "NutriBulletRx Short Cup". Just a heads up that there is no way that all the ingredients suggested in some recipes will fit in the "short cup". Example given, the "All Vegged Out" recipe that is supposed to be their equivalent of V8 Juice. Fortunately I have the Oversized Cup to work with. I suggest halving most of the recipes for the short cup first time around. With all recipes, they're just starting places.
