I bought this blender for the sole purpose of making smoothies. I was quickly disappointed. Unless you use small, crushed ice, then it is almost impossible to get the ice to crush to make the smoothie. After you put the ice cream on top of the ice, it almost shuts the blender down. The Proctor Silex 7 speed just is not designed for it I guess. I am not sure why it is designed so poorly. You go through the seven speeds, one of them being crush, you would think it would crush the ice to make a smoothie but it does not. I have never been able to make a good smoothie with it. I use it to puree apples to make applesauce and it works well for things like that. It just isn't what I bought it for but at least I get some use out of the money I spent on it. I guess you can't win them all! My best advice is to buy it only if you are looking to blend soft things and not hard things like ice cubes! Just not much of a smoothie maker!
