Very simple operation, top result.

The disadvantage I feel that it the device - if you have it turned on only once - may not turn again to provide for example additional parts into it.

You have to make sure that all parts were to be sterilized thoroughly cleaned! One does not observe that water may drip with milk residues on the hot plate and these very dirty (baked milk). The filled it and to be disinfected parts are then not naturally disinfected properly.

But all in all a good thing.
