I have had this for about a year and only used it a half dozen times to make mayo, salad dressing and whipped cream. The inside of the blade part fell apart and I believe it is broken. It is an expensive hand held mixer for this poor of quality. I have other products that are All Clad that I love, like my frying pans, but unfortunately I am sorely disappointed with this particular product and will likely go with the Breville immersion blender next time.
