I received this blender as a gift for Christmas from my brother. This past week I have been doing a Shed Challenge with my business. We prepped last week so making our green smoothie would be easy. We put the prepped bags in the freezer and took it out first thing in the morning. I really thought there would be NO WAY that this blender could break up the ingredients frozen but it did. It also was super easy to hand wash. I learned a trick that after you rinse-squirt a small amount of dish-washing liquid in hot water, put it back on the blender and blend at high speed. It cleans it for you! All you have to do is rinse! This blender far exceeded my other blender.
