For two months in operation, enthusiastic for two months and every day again five stars. The device has been described and praised here already extensively. Philips recommends fresh, cold milk with 1.5% fat for particularly successful milk foam. I've tried this milk frother with cold, with warm rooms, with long-life milk, fresh milk, with 1.5% and 3% fat milk - always sensational and tastier foam. My standard: UHT milk, cold from the refrigerator and 3% fat. Is the easiest of the Voratshaltung as we otherwise use this milk. Small deficiency: The mark inside the max. Filling level is difficult to detect, especially if the device is at a not so well-lit place. Then you have to lift the unit out of the bracket, go to the light, fill milk, back to the station, and Start. But the reward is so great the milk foam. And cleaning is a matter of seconds. Really.
