Due to the many positive reviews, I had ordered a year ago two of these milk frothers,
One leading the way: yes, the device can foam milk.
The bar at the end of the foamer is mounted, is made quite thin metal.
None of the two foamers this rod was 100% right.
As long as the batteries have full power, which is hardly noticeable.
But after that the unevenness was noticeable and the frother vibrated / wobbled only with considerably reduced speed. Makeshift I could manually stop the vibration, as I briefly above the foamer took the metal bar between his fingers.
Over time, the vibrations grew stronger, and at some point I have only to a foamer and then disposed of the other.
For three months I have again a frother in use, the frother and bar is much more robust.
Since there is no such problem. And in my opinion the foamed milk even tighter.
