I've been using the new Vitamix A2500 for a couple weeks now, and I'm absolutely loving it. It's sleek, quiet and easy-to-use. I love the auto-clean option - makes clean up a breeze. I've also been enjoying the pre-set program for making smoothies. I'm able to set to the smoothie setting and walk away. When the machine turns off, I can trust that my morning smoothie will be perfectly blended. I was sent this machine in exchange for a product review. All opinions are my own.
