I have been jealously leering at the newer Vitamix blenders with their smoothie cups. Not ready to give up my older (yet still reliable) Professional Series 750 Vitamix, I was so happy to see this is available! I love this! It works great! The only caution I have is to make sure the smoothie cup is securely screwed into the base. (A test tip over the sink is worth the short time it takes.) But, I have put ingredients up to the top, and my Vitamix dutifully grinds (ice cubes) and blends to perfection. So happy I got this!
