Query: not happy with performance

I needed a new blender and was looking for something that would crush ice for snowcones and make great milkshakes. The box on this one said had a sabre blade for snow cone ice. To find out to crush ice, you have to add water which make is pure mush and real watery,especially after you add the flavoring. The kids did not like the snow cones. As for milkshakes the ice cream gets stuck at the bottom so you have to keep opening it up to stir. Several times it has leaked out from the bottom. I will be returning it.
