Our Braun stick does not get a regular workout and it has lasted years.
Smoothies with frozen fruit are made in a heavy duty blender (vitamix)
hummus is usually made in an ancient cuisinart food processor.
I have not found the braun's whisk to be helpful but we like the blade & container attachment
here are their current models
