By far, this is the one tool I MUST have in my kitchen. The Vitamix beats the Blendtec (which I used to have). It makes the smoothest anything (soup, ice cream, hummus)! They are very expensive but worth every penny.
This baby is so handy. I use it to whip up quick dressings and to blend flax seed. I could survive without it, but it would be more inconvenient to have to use my Vitamix for such small tasks.
