Bought our Vitamix last year. My husband really wanted it and I finally gave in. At first I didn't know what to do, but just experimented with everything. We use it for veggie smoothies. We also have another very expensive Brevel blender...doesn't work as well as our Vitamix.
If you're going to get one, just be sure to commit to learning what to put in it and how it best serves you. I had buyer's remorse for the first month, but now use it daily.
