The Ninja Professional Plus Blender with Auto-iQ technology is an impressive kitchen appliance. Using it is remarkably simple and it works incredibly well. It is extremely powerful, yet quiet, and blends drinks quickly and very efficiently. The lid locks in place, preventing spills while blending or pouring. Cleanup of the pitcher and blades is very simple. This blender affords all of the features you need in a very simple, sleek unit. From frozen mixed drinks to smoothies and milkshakes, I highly recommend this product!
