I got the Hamilton Beach Wave-Action 48 oz. Blender a few week's ago.  
The Wave Action is designed to pull whatever mixture you have put into the blender into the blades to make the mixture smooth.
It makes excellent smoothies. 
I also make plain low calorie milkshakes with milk, extract flavouring, and ice.  
This blender crushes the ice and mixes the ingredients well to make the milkshake thick.  
I am very satisfied with my 700 watt blender.
The blender is very easy to clean and I love the glass jar.  
It is dishwasher safe.
The lid has a pour spout which can be used to pour items into the glass jar. 
There is also a plastic filler cap used to add whatever you choose to the glass jar for blending. 
It also comes with a very sturdy stir spoon. 
I am quite happy with this Hamilton Beach Wave-Action Blender and I love the metallic red colour. 
I received this blender gratis, as a Hamilton Beach All Star Ambassador.
