The milk is super foamed and heated. Also the cocoa tastes great !!
The vessel is to clean stainless steel and easy. The Agitator is driven by a magnet and it is just a small guide on the ground. Thus there is no risk that milk may leak downwards since the case is closed.
The fact that there is no cover for the device, does not bother. The milk remains where it belongs.
The one point deduction I give only because sometimes some milk from burning down. Not much or particularly bad, but just a little. Most, if multiple servings foams successively directly.
I would recommend the device only !!
