I have had my Vitamix A2500 for around two months now and have used it many times.  I've made lots of smoothies, some sauces, tried my hand at peanut butter, and have used it in pureeing.  I can say that I am very happy with how it performs. It makes the smoothies smooth and it does a great job of grinding up cashews in a soup base. The only thing I've ever had an issue with is doing ice cream or pureeing lentils. The contents gets real thick and it's hard to keep it moving. I've had it give me an error message after that but I just let it cool down and it's seemed to have worked fine ever since. I bought it mostly to use in my new eating of Nutritarian eating. It is working very well compared to my old Oster brand mixer.  That one didn't chop up the spinach as smooth or even the cashews in a soup base. I am very pleased with my purchase and look forward to many years of use from it!
