I love this blender. I have had it about 9 months and use it daily- sometimes twice a day! I often put the cups in the dishwasher and they show no signs of getting damaged by the dishwasher. I bought it to make smoothies for my daughter for breakfast because it is hard to get her to eat a quick healthy breakfast- I use 1 cup fruit, 1/2 cup yogurt, 1/2 cup milk and honey. My other big use now is that I use it for Almased smoothies for weight loss- blends it very well with ice and flax seeds as well. I just bought a second unit for our vacation home because I can't live without it! The only bad thing about it is that it is very noisy- I recommend you turn it on and walk away! You cannot use it in the morning without waking up the whole house. But I will not rate it lower for the noise since if it wasn't noisy, it wouldn't have the power that it has.
