The creamer provides a very short time a stable foam may therefore also keep the batteries a long time - until three weeks without any noticeable drop in performance would be recognized. The frother used with me four times a day. If you press the button in the center, it runs in continuous operation. A second press in the middle immediately interrupts the continuous operation. Pressing them at the bottom, you can foam in the interval. The frother makes a stable, high-quality impression. The stainless steel case is coated with paint so that it touches comfortable and the usual on steel gray fingerprints therefore not arise. The included stand is handy for placing the device. So far, this device is the best of all that I've ever had. This I have been 3 weeks in use.
