I bought the milk frother Severin as a gift and wanted to try him before the taverns once. I own the Nespresso Aeroccino. First, the milk frother Severin is greater than expected, the dimension is about that of a kettle. However, for it fits into a lot of milk - enough for two to three cups. The Nespresso Aeroccino summarizes much less milk and is barely enough for two cups. For the Nespresso machine has an overall higher quality impression. The Severin device rattles a bit annoying during foaming and it takes longer for the milk foam is ready (about 30 sec at Nespresso, ca 1 min 20 sec at Severin). By foaming the milk faster bakes the Nespresso machine but almost always on what did not happen when Severin device. Giant Plus for Severin is also that the device is in two parts and the milk jug can be cleaned in the dishwasher. The milk foam is great and absolutely comparable with both devices. Conclusion: If you want to make milk froth often for more than one person, the Severin-machine answers. Who does usually only for milk foam, has a smaller kitchen and emphasis on styling, should increase the Nespresso machine rather. I'm going to the Severin-frother in any case give with a clear conscience and consider it a good device.
