Does not froth milk even nearly as well as other units, even much cheaper ones. The "frothing disk" makes milk spin like crazy but creates very little foam. "Soft Touch" button very difficult to hold down for the required time to keep unit turned on. Position of the button on top requires holding it with a clenched fist which is very uncomfortable because of the force required to hold the button. I'm returning it.
