I had read the book about green smoothies and started making them with my old blender; but there was always chunks in it, no matter how well I thought I blended the smoothie. My daughter got me a Vitamix from Amazon and I just LOVE that blender ! ! It blends everything until it is totally smooth and silky. I can soak almonds overnight and the next day, I make fresh almond milk in the blender, and with the Vitamix, I never even need to strainit because there is nothing left that needs straining, just the creamy almond milk. I also make fresh lemonade every day, using a fresh lemon, some ginger and a little turmeric powder. It is so healthy and delicious, I know that the Vitamix blenders are expensive; but they last forever, and they do the best job of any blender you can buy. Mine is a refurbished one, and even it has a 5 year warranty.
