This arrived right in time for me to make fresh salsa. The assembly was simple and easy to put together, and using it was a breeze. It is not a constant blend, rather a pulsing blender that operates by pushing a button until you achieve the blend you desire. It comes equipped with the blender and a container with a lid for blending and storing. This is a powerful hand blender that blended this delicious salsa in minutes. I am excited to use it for more things like soups and smoothies!
