This Black and Decker PowerCrush blender is a big powerful blender. I have made smoothies and milkshakes which have been blended so smoothly. There haven't been any chunks of fruit or ice in any of the drinks I made using this blender. I like the preprogrammed buttons which makes this so easy to use. The single serve blender jar that was included is great too. I wish I had two of these since everyone likes using it. It is a great added feature. While I am not sure what quiet technology means concerning this blender since I don't think any blender can be quiet while crushing ice, this Black and Decker one isn't overly loud. The only con about this great blender is that it is rather big and takes up my counter space but I like it a lot so I will make room for it . [This review was collected as part of a promotion.]
