The first bar-Whip has nevertheless kept more than five years. On average, it was twice a day in use. Some time ago he made before limp because good battery awakened him (I like the Eneloop) and a little contact spray back to life. Now he's finally in Schäumerhimmel. Not so great, I always found the labbe engined power button without pressure point and the sliding, wobbly battery cover with spring clips as a contact rail. On a positive note: the spiral is easy to clean directly after use under running water. Because the Latte-Whip indisputably makes a first-rate foam, I ordered him back to me, although much more expensive than competing products. Lo and behold, the battery compartment is redesigned. Well then, to hope again five years.
Addendum: After the second bar-Whip has held less than three years, I have reduced my rating to three stars and now opted for a clearly better competitor.
