I've had my Vitamix about a month now.  I am thrilled with it.  I've mainly used it for smoothies.  I had 3 previous versions of another popular brand and there is no comparison.  I wanted smoothies that were more like a juice, especially without chunks, but don't want the hassle of a juicer.  The Vitamix makes the smoothie exactly how I want it.  If I had one wish, I would only wish it was just a little quieter.  Noise is a fair exchange for the power I get from it though.
