High performance, very strong performance - so strong that I distributed the milk in the first Aufschäumversuchen from the cup out in all directions. Bin after a few trials now come behind the secret: who is like I was used to a very weak and easy foamer, should change here: the Bestron's easy to keep upright in the middle of the milk, which the "whisk" about 1-2cm in milk immersed. The creamer has at the top a button, which can only very briefly tapping the best with your thumb (do not hold). After a few short keystrokes, the milk is frothy. Great part with an Italian flair, thanks to the heavy casing, the ergonomics and an elegant metallic suspension for standing. Addition to "long-term behavior": within the first 3 months there were no complaints. But then (even the first rechargeable battery pack) suddenly of total failure: the frother was broken - engine failure, almost beyond repair, and with only moderate use (5-10 times per week). Given this short pleasure I have to deduct 3 stars for the short lifetime.
