We had very high expectations and this machine definitely lives up. It is much quieter than I expected for the motor size, probably half as loud as our kitchen-aid, which isn't nearly as powerful. Blends up even the tiniest seeds in a smoothie for a perfectly uniform consistency. VERY we'll built, simple and is actually easy to clean. The cookbook, 'Create', which I thought would be a silly sales gimmick is actually a beautiful, colour hardcover with all kinds of great recipes that are useful, as well as provide nutritional info. Keep in mind the wider, shorter container with these models may have difficulty blending small amounts.
