2 stars because I am looking for a stove without plastic inside. Otherwise 4 stars. Plastic and silicone is inside Installed - The first time it smelled like plastic. The outer surface is not as fast as some other dirty argue. It empties the last 1-200ml from so there is the boiler in an inclined position, which is sufficient to cover the closing by gravity - hold Manually open. Emptied to the cooker remains still standing water (~ 30ml) even if one puts it on the head - Reason: There are adding components in the boiler. Design is very good.
