1) A lot of power! The speed does not drop when the foam has formed, but remains nearly constant high. Of course, the risk of spilling during use is available directly in a cup, but in my opinion, in the nature of things. With interval switching and / or over the sink but that is not really a problem.
2) device is pleasantly light.
3) device can be easily switched on and off via the side buttons, switches has good tactile feedback.
4) The battery lasts a long time. Even after repeated use full power equipment available. Have asked for charging in the charging station the unit. If the device is constantly in the station, which is anyway not an issue. The part is the way without charging station neatly on the countertop or wherever.
5) The rack on which the spiral sits, can not bend as they wegfedert under side loading. Very good solution and, above all, important as a bent rod rotate unclean and device performance would deteriorate.
Although 6) Design is not worthy of an award. The appearance is yet to be described as pretty and was supposed to be like any or acceptable.
7) For life, I no estimate, but after 5 weeks, since I use the device, no signs of wear can be seen.
8) The price is okay, especially supplied a charging station is included (no battery replacement).
Conclusion:
I would not hesitate to re-purchase this milk frother and also give without hesitation.
