We absolutely love our Vitamix! We use it to make soups, purées, smoothies, etc. We have used the warranty because of so much use that the motor gave out! Vitamix honored the seven-year warranty and refurbished the unit for us! Highly recommend!
We have had our Vitamix for probably 15 years. There are various models, ours is one of the cheaper models, but it has been terrific. Early on, we had an issue (and I can't remember now what that issue was) and customer service was great. We shipped in a box they provided and we never had another issue.
We really love our Vitamix I have had it now for 7 years and still going strong. I have been even juicing with it over the passed few months and have now discovered a new way of using it. It is really worth the investment.
We probably use our Vitamix everyday, if not close to it. We use it to make smoothies most of the time. But I do use it to make soups as well. I also use the smaller container to make hummus and peanut butters. It can blend pretty much just about anything.
