Must have kitchen tool - an immersion blender

This is one of my favorite kitchen tools that simplifies tasks. This is a favorite on Amazon and my Braun stick blender came with a whip attachment. By immersing the 'stick' in a soup pot, it blends what is under the round cup at its base. I lift and place over and over again until the soup is lump free and smooth. No longer do I have to manage pouring hot liquid into a traditional blender. The whip attachment makes great fluffy beaten eggs and egg whites. The clean up is easy. I don't want to own gadgets that I seldom or never use. This one is a must have tool!
