it boils water. as expected.
not particularly fast, but no slower than 10 kettle.
Now for the shortcomings
1. After a short time put the black plastic parts on the cover unsightly chalky deposits on - even though the water contains hardly lime. Such stains can be removed if at all eliminate only with much difficulty, as they establish themselves in small cracks.
look there.
2. After approximately 6 months mucked the cooker a little (let not power) and then gave the whole to mind.
Overheat protection probably burned through.
shame about the beautiful part. def. no recommendation!
