My infant daughter has severe eczema and so I've had to go on a strict elimination diet for 9 weeks and counting as I slowly reintroduce foods. I had been waiting years and years to buy a new blender, and I knew I wanted a Vitamix to make truly smooth blends. The 10 year warranty on the Ascent models made the choice for me. I am SO SO glad to have had another way to get my nutrition when it feels like I've been so deprived. Adding spinach or carrots to my fruit smoothie with some collagen powder has made this time so much easier. Be careful not to overdue it will ingredients (the vitamix can handle it easily, but your gut is not made to process that volume of fiber - and it's easy to add to much sugar, even in the form of fruit). Very satisfied with my purchase!
