The Hamilton Beach Smoothie Maker is to use and convenient. It’s nice that it comes with 2 blender cups. The only thing I don’t like is that these cups are on the go cups but the blades are still attached when drinking. This can be hazardous. I wish the machine came with a separate on the go cup. My kids like this machine a lot and have been making there smoothies in this blender. It’s easy to use and clean the machine.
