ok does its job

Involvement:General (knows how to use it) - Ownership:more than 1 month

Easy to use
Uses regular AA batteries (x2)
Awesome to make that cappuccino milk foam
Great for mixing drinks and kid's milk chocolate

Build quality should be a bit little better and it would be perfect.
Its not like it has a bad shit quality.. its just that it could have a better one..

: This is how I learned to use it (from a Austrian friend).
1. Take a bit of milk to the microwave for about a minute, making it really hot but not boiling.
2. Mix the milk with this device by starting at the very surface of the hot milk.
Use a deep container (like measuring jars) b/c the foam should end up 5 times the volume of the original milk.

Great cheap and practical kitchen appliance.
