I have had my for 3 years now, I have used it and have loved everything I made!! I go to my local home and garden show just to watch the vitamix demo!  and look at the new recipes and samples!  I was so tempted to get the new dry/wet blade combined!!  I know I will never need to replace mine.  I may have to give it away! This machine has changed how I eat and my health has soared!  I am a forever vitamix fan!!!  thank you!
