A couple of weeks ago, my mother bought me a Vitamix blender. It is a very high powered blender that can do much more than a regular blender. I had seen them demonstrated at Wegman's when I went and they were doing all kinds of things with it. The thing is pretty costly, and I was not going to buy one for myself, so when my mom called and asked me if I wanted one, I accepted.
This morning I made myself a green smoothie made from a frozen banana, two large kale leaves from the garden, some almond milk (also made in the Vitamix), a teaspoon of flax seed, and a half a mango. It was delicious and I understand very nutritious. My only complaint is that the bottom does not come off unless you have the special tool and that makes it a little hard to clean unless you make something that is mostly liquid. My regular blender does that and it is very convenient for cleaning.
I have not done many of the things that the rather lengthy instruction manual suggested and I may not ever use it totally to its potential. For example, you can even grind grains, which I may try if I ever grow wheat. But it sure grinds up a frozen banana quite efficiently.
