This is always annoying with devices. Sometimes CH, sometimes with an adapter, sometimes nothing... Digitec/Galaxus should really improve. The kettle above came with a D->CHF adapter.
Only the bottom is made of chrome steel. The rest (except for what is visible from the design at the top) is made of plastic. I bought this kettle in January 2014 with a Swiss plug. It is used a lot and does what it promises. I would always choose this kettle again (with different temperatures - depending on the type of tea etc.).
