This SmartPower blender by Cuisinart has all the qualities of a great blender. It's powerful, easy to use, sturdy, and efficient. The tight-fitting cover can be pressed on without turning or twisting it into place, and we found that it did not leak even under heavy use. The 2-ounce pour lid allows you to measure and add ingredients neatly without removing the cover. The 40-ounce glass jar has a wide mouth to allow chunky ingredients to be poured. The locking ring is self-aligning, so the glass blender jar slides easily into position, and the leakproof rubber gasket holds the glass jar snugly in place for safe operation. High-quality, patented stainless-steel blades are strong enough for all bar blender tasks, from crushing ice to puréeing fruit. The heavy-duty motor base is strong enough to crush ice without liquid and is backed by a three-year warranty. The seven-speed touch pad control with indicator lights is easy to use and offers great versatility and a range of blending power. The pulse button allows you to pulse at any speed, for tighter control as you blend.
